Crisis On Infinite Earths (Arrowverse)

"Crisis on Infinite Earths" is the sixth Arrowverse crossover event, featuring episodes of the television series ''Supergirl'', ''Batwoman'', ''The Flash'', ''Arrow'', and ''Legends of Tomorrow'' on The CW. The ''Supergirl'', ''Batwoman'', and ''The Flash'' episodes aired in December 2019 while the ''Arrow'' and ''Legends of Tomorrow'' episodes aired in January 2020. The events of the ''Black Lightning'' episode " The Book of Resistance: Chapter Four: Earth Crisis" (which aired between ''Batwoman'' and ''The Flash'') and a two-issue comic book with characters and concepts unused in the live-action episodes also tied into the event.

"Crisis on Infinite Earths", inspired by the comic of the same name, continues plotlines established in the previous crossover, "Elseworlds". The preceding episodes of ''Arrow'' season eight and much of ''The Flash'' season six serve as a prelude to the crossover. In "Crisis", the Monitor gathers Green Arrow, the Flash, Supergirl, Batwoman, Sara Lance, Ray Palmer, and several others from throughout the multiverse to stop the Anti-Monitor from destroying reality. The crossover's events result in the Arrowverse being rebooted, affecting all of the series.

Initial references to the crossover began in 2014 with ''The Flash''s pilot episode. The adaptation began in earnest during the development of "Elseworlds", and the crossover's title was revealed at the end of "Elseworlds" in December 2018. Casting was announced in mid-2019 and included actors who previously portrayed DC characters in other media, such as Burt Ward and Kevin Conroy. Cress Williams from The CW series ''Black Lightning'' crossed over with the Arrowverse for the first time, and other actors reprised their roles from various DC film and television series. The event was filmed from the end of September to the beginning of November 2019.

"Crisis on Infinite Earths" was critically praised for its scope, ambition, and the many cameos, though the fate of Oliver Queen had a mixed reception. The crossover proved popular, as each episode gave season-high ratings to its corresponding series. A two-episode aftershow, ''Crisis Aftermath'' hosted by Kevin Smith, aired after parts one and three to explore the crossover's events. "Crisis on Infinite Earths" was intended to be followed by a crossover between ''Batwoman'' and '' Superman & Lois'' in 2021, but this did not occur because of the COVID-19 pandemic, being replaced informally by David Ramsey appearing as John Diggle on multiple Arrowverse series. The next crossover, "Armageddon", occurs over the first five episodes of the eighth season of ''The Flash'' in November and December 2021.

Synopsis

Prelude

To prepare for the coming crisis, the Monitor recruits Oliver Queen and Martian Manhunter and sends the former on missions to collect a variety of items, while he retrieves the body of Lex Luthor and revives him. Meanwhile, Barry Allen and Iris West-Allen learn that the crisis date has moved up to December 2019 and that the Flash must die to save billions of lives. Barry travels to Earth-3 to see Jay Garrick and Joan Williams, who have been tracking antimatter signatures across the multiverse, to learn more about what happens to him. They send Barry's mind forward in time, making him see billions of timelines where the multiverse is destroyed and one where he dies saving it.

While on a mission, Oliver witnesses the destruction of Earth-2 from an antimatter wave. In Star City, William Clayton, Connor Hawke, and Mia Smoak time-travel from 2040 to the present, while Oliver and John Diggle learn that Lyla Michaels has been working with the Monitor. Moments before the crisis begins, Nash Wells is pulled into a chamber under Central City after he is promised a new life. As the crisis starts, the sky over Central City and Lian Yu turns red. Lyla, now a "harbinger of things to come", collects Oliver and Mia on Lian Yu.

On an unspecified Earth, the sky also turns red over Freeland and adversely reacts to Jennifer Pierce's powers, tearing her between her Earth and those of two of her doppelgängers. As the Pierce family and Peter Gambi try to bring her back, the antimatter wave overtakes them while Jefferson Pierce is transported away.

Plot

Having already destroyed countless parallel universes, the antimatter wave makes its way to Earth-38. Brainiac 5 detects the wave approaching Argo City, prompting Kara Danvers to warn her mother Alura Zor-El, her cousin Clark Kent, and his wife Lois Lane. Clark and Lois send their son, Jonathan, off in an escape pod just before the wave hits. Harbinger brings Oliver, Mia, Barry, Kate Kane, Sara Lance, and Ray Palmer to Earth-38 and rescues the Kents from Argo. As Harbinger briefs the heroes on the situation, the Monitor raises a tower to impede the wave while the DEO and Lena Luthor evacuate Earth-38's inhabitants. Brainy finds Jonathan's pod on Earth-16, so he, Lois, and Sara leave to retrieve him while the others fight the Anti-Monitor's forces. Preparing to die, Oliver passes the Green Arrow mantle to Mia. When he learns that Barry is fated to die, however, he argues with the Monitor about their deal. The heroes fight a demonic army until the Monitor breaches them off-world. Refusing to leave, Oliver nullifies the Monitor and stays behind to protect the exodus. Lois' team returns to Earth-1 with Jonathan just as the Monitor brings a dying Oliver to say goodbye. Nash, now a " Pariah" for releasing the Anti-Monitor, announces that events have changed and all is lost.

Harbinger recruits Earth-74's Mick Rory so the heroes can use his ''Waverider'' as their headquarters. Following Oliver's death, the Monitor consults the Book of Destiny and learns about four of seven Paragons: Hope (Kara); Destiny (Sara); Truth (a Superman who has suffered "more than any mortal man"); and Courage (the "Bat of the Future"). Clark, Lois, and Iris locate the second Superman on Earth-96, where Lex uses the Book of Destiny to brainwash that Earth's Clark until Lois knocks Lex out. Kara and Kate travel to Earth-99, but fail to recruit its Batman after discovering he murdered his world's Superman while Sara, Barry, Mia, and John Constantine take Oliver to a Lazarus Pit on Earth-18 in an attempt to resurrect him, only to learn his soul is missing. On the ''Waverider'', the Monitor has Ray build a "Paragon Detector", which identifies Kate as the Paragon of Courage. Elsewhere, Harbinger is secretly contacted by the Anti-Monitor.

The Paragon detector identifies Barry as the Paragon of Love, J'onn J'onzz as the Paragon of Honor, and Ivy Town scientist Ryan Choi as the Paragon of Humanity; Iris, Ray, and Ralph Dibny leave to recruit Choi. After the Monitor restores Cisco Ramon's powers, he, Barry, and Caitlin Snow meet Pariah in the Anti-Monitor's chamber and find an anti-matter cannon powered by Earth-90's Flash. When Cisco frees Barry-90, the cannon goes critical, so Pariah recruits Jefferson from his recently destroyed Earth to contain its energy. Barry-1 volunteers to destroy it, but Barry-90 stops him, saying that the Monitor did not specify which Flash would die, and sacrifices himself in his place. Meanwhile, Constantine, Mia, and Diggle visit Lucifer on Earth-666 for help entering purgatory and retrieving Oliver's soul. Before they can leave, a Spectre named Jim Corrigan appears and beckons Oliver to come with him, forcing Constantine's team to return to the ''Waverider'' without him. Suddenly, the Anti-Monitor sends a brainwashed Harbinger to kill the Monitor so he can absorb his power and finish destroying the multiverse. Before he is killed, Pariah sends the Paragons to the Vanishing Point, where they witness Lex replace Superman-96 with himself using a Book of Destiny page.

On the planet Maltus 10,000 years earlier, Mar Novu attempts to see the birth of the universe, only to end up in the antimatter universe and reveal the multiverse's existence to the Anti-Monitor. Back in the present, following the multiverse's destruction, the Paragons struggle to survive at the Vanishing Point. Once Corrigan teaches him to how use the Spectre's power, Oliver goes to the Vanishing Point to rescue the Paragons and strengthen Barry. Barry drops off Kara, Choi, and Lex on Maltus, but temporarily loses everyone else in the Speed Force after an encounter with the Anti-Monitor. Kara and Choi convince Novu not to implement his plans before Barry takes them and the other Paragons to the dawn of time. There, they learn that the Anti-Monitor will always learn about the multiverse's existence because they only stopped one version of Novu. The Paragons battle the Anti-Monitor and his shadow demons until Oliver uses the Spectre's power to restore the multiverse while the Paragons provide help via Lex's page. Despite succeeding, Oliver dies once more, with Barry and Sara at his side.

In the recreated universe, the Paragons discover only they remember the crisis and that Earth-1, Earth-38, and Jefferson's Earth were merged into Earth-Prime. J'onn uses his psionic powers to restore their allies' memories while Sara tries to find Oliver. When the Paragons are attacked by demons, a restored Nash discovers that the Anti-Monitor is still alive and plans to resume destroying the multiverse. Nash, Ray, Barry, and Choi develop a bomb to shrink the Anti-Monitor and send him to the microverse. Barry, Kara, Sara, Kate, Clark, J'onn, and Jefferson hold a memorial service for Oliver and agree to protect their new world in his memory.

Production

Development

"Crisis on Infinite Earths" was first hinted at in the Arrowverse in the pilot episode of ''The Flash''. In September 2018, three months before the release of "Elseworlds" (the Arrowverse crossover in the 2018–19 television season), ''Legends of Tomorrow'' executive producer Phil Klemmer said that the next crossover had "a loose shape". In early December 2018, a week before the airing of "Elseworlds", ''Arrow'' showrunner Beth Schwartz said that the producers of all the series "already know a lot about what's going on in next year's crossover"; according to Marc Guggenheim, "Elseworlds" would "lay the groundwork" for it. The end of "Elseworlds" revealed the crossover title and premise as "Crisis on Infinite Earths", adapting the story from the comic of the same name. "Elseworlds" introduced the characters Mar Novu / Monitor and Psycho-Pirate, and alluded to an impending "crisis".

In January 2019, ''The Flash'' showrunner Todd Helbing said that the remainder of the fifth season would contain elements of the upcoming crossover. The CW president Mark Pedowitz called the crossover "the biggest, the most complicated one" to date, and was hopeful that ''Legends of Tomorrow'' (which did not participate in "Elseworlds" because of production complications) would be part of "Crisis". In May 2019, Pedowitz announced at The CW's upfront presentation that the crossover would include ''The Flash'', ''Arrow'', ''Supergirl'', ''Legends of Tomorrow'', and ''Batwoman'' in a five-episode event spanning late 2019 and early 2020. The crossover occurred in the ninth episodes of ''Supergirl''s fifth season, ''Batwoman''s first season, and ''The Flash''s sixth season, in the eighth episode of ''Arrow''s eighth season, and as a special episode of ''Legends of Tomorrow''s fifth season which had not yet begun airing; this episode is not considered the series' season premiere. Guggenheim said that when they first presented the crossover to the studio and network, the creators stressed that they did not want the event to be "Crisis on CW Earths" but "to touch as many strands of the DC tapestry as possible." About the crossover's comparison to the Marvel Cinematic Universe film '' Avengers: Endgame'' (2019), Guggenheim said "for Barry and Oliver, there is an emotional denouement that is reminiscent of ''Endgame'' ... ''Endgame'' is an exclamation point. 'Crisis' is a semicolon".

Lead-up

The May 2019 season finales of ''The Flash'', ''Arrow'', ''Supergirl'', and ''Legends of Tomorrow'' contained hints of the upcoming crossover, with the Monitor appearing in all series except ''The Flash''. ''The Flash'' season six showrunner Eric Wallace said that when all the series' showrunners discussed plans for their series before the crossover, "all of this synergy started to happen" with "a lot of cross collaboration" in service to the crossover's events. Wallace felt the themes of grief, death, and the end of all worlds in "Crisis" worked with the story they were trying to tell in season six of ''The Flash'' of villain Ramsey Rosso / Bloodwork, "who is facing the end of his own world". This allowed the season's start to help set up the crossover.

Most of ''Arrow''s eighth season is a prelude to the crossover. The ''Arrow'' writers consulted with their counterparts on ''The Flash'' about the destruction of Earth-2 in "Starling City" to ensure that they could destroy this Earth. On ''Supergirl'', co-showrunner Robert Rovner said that the season would tease the crossover "in our way, which is a little bit different from the way ''Arrow'' and ''The Flash'' are doing it". Rovner cited the return of Malefic ( J'onn J'onzz's brother) as a major plot thread leading to the crossover, calling it "a gauntlet for J'onn". LaMonica Garrett, who portrays the Monitor and the Anti-Monitor, said before the crossover that the Anti-Monitor's "presence ouldbe felt before you physically see him ... You see just enough of him to know this guy means business, but it's not in your face in every scene leading up to" the crossover. The preceding episodes of ''Batwoman'', ''Supergirl'', ''The Flash'', and ''Arrow'' contained a tag scene of Nash Wells accessing a chamber under Central City.

Tie-ins

The ''Black Lightning'' episode " The Book of Resistance: Chapter Four: Earth Crisis" tied in to "Crisis on Infinite Earths" before Jefferson Pierce first appeared in the crossover's ''Flash'' episode. In the ''Black Lightning'' episode, a red sky covers Freeland before anti-matter strikes Jennifer Pierce and sends her to a void where she finds her Earth-1 and 2 counterparts. An anti-matter wave wipes them and her Earth out, except for Jefferson, who is transported to an unknown location.

The crossover story was expanded in a two-issue comics series ''Crisis on Infinite Earths Giant'', written by Marv Wolfman (who wrote the original 1985 series) and Guggenheim, and illustrated by Tom Derenick, Trevor Scott, John Kalisz, Andy Owens, Hi-Fi, Tom Grummett, Danny Miki, and Chris Sotomayor. The series reprinted material from the original ''Crisis on Infinite Earths'' comic, and its second issue included material from ''DC Universe: Legacies'' #6 (2010). About the series, Guggenheim said that its concept "came pretty early on in the process" when it was realized that the story's scope would exceed the five episodes. By creating the comics, it allowed the producers to utilize "all of the characters that we don't have in the crossover proper for logistical reasons, or financial reasons, or creative reasons... he comic seriesallows us to tell a major piece of the story that we're designing, with characters and concepts that we couldn't achieve in live -action". Its four main characters are Felicity Smoak, the Ray, Nyssa al Ghul, and Wally West, in addition to appearances by Atom, Sara Lance, Batwoman, the Flash, the Monitor, Lex Luthor, and others. Serious consideration was given to the Huntress, but Guggenheim opted for Nyssa al Ghul because "we had done a comic-book tie-in that bridged seasons two and three of ''Arrow'' and untresshad featured prominently in that, so Nyssa had not yet had her chance to be immortalized that way". Wolfman added that the comics were "created to tie in perfectly with The CW shows" so it felt like a main part of the story and not ancillary: "This is integral to the entire storyline." The first comic debuted at Walmart on December 15, 2019, with the second releasing on January 19, 2020; both were released in comic stores the following month. The series is set during the first part of the crossover's ''Batwoman'' episode. Its stories and behind-the-scenes extra content was published in a deluxe hardcover edition on July 7, 2020.

Writing

The ''Supergirl'' episode was written by Derek Simon and Jay Faerber, with Robert Rovner and Guggenheim contributing to the story; Don Whitehead and Holly Henderson wrote the ''Batwoman'' episode; and Lauren Certo and Sterling Gates wrote ''The Flash'' episode, based on a story by Eric Wallace. The ''Arrow'' episode was co-written by Wolfman and Guggenheim, and the ''Legends of Tomorrow'' episode was written by Keto Shimizu and Ubah Mohamed.

The writers gathered for a two-week session to work on the crossover. Guggenheim, who was the overall creative for "Crisis on Infinite Earths", began by creating "a series of big tentpole beats that could happen in each of the five hours". These moments were designed to be modular and could be moved throughout the episodes depending on each series' creative needs, actor availability, and other factors, while also determining episode order. Guggenheim's initial template had ''Arrow'' as the fourth hour and ''Legends of Tomorrow'' the fifth, "because in crossovers past, ''Legends'' has always been the finale of the crossover". The CW requested that ''The Flash'' be the third hour and after working "out those tentpoles, for a variety of different plot reasons, it made a lot of sense for the first hour to be ''Supergirl''". ''Batwoman'' was the second hour. Certain characters were considered "integral", while others would make cameo appearances, depending on actor availability.

With the large moments determined, the writers separated to write each episode. The group reconvened to review the whole, making adjustments as necessary. Each series' writers would work on its title character's scenes, to ensure consistency. For scenes set in Gotham City, ''Batwoman'' showrunner Caroline Dries retained the series' grounded tone because it was "not normal for he characters of ''Batwoman''to interact with aliens and travel to different universes". Although the crossover is considered "a five-hour epic", the title character of each series and characters appropriate in those worlds (such as Barry Allen of Earth-90 appearing on ''The Flash'') are highlighted. The episode scripts were completed by early September 2019.

The original comic was created to help with DC Comics' continuity problems; since the Arrowverse does not have those, however, the crossover allowed its creators to focus on the characters and their interactions. Supergirl and Batwoman's relationship was developed, after it was seen at the end of "Elseworlds" that "those two characters resupporting each other much in the same way that Barry and Oliver have been supporting each other in previous crossovers". This version of the Anti-Monitor was inspired by the character's appearance in the New 52 "Darkseid Wars" storyline. Sara Lance is the focus of the ''Legends of Tomorrow'' characters, with the crossover "kick ngoff Sara's emotional journey for season 5 of ''Legends''" and giving Sara "a different perspective on things".

Guggenheim said that the crossover would try to incorporate "seminal moments" from the comic book, opening with a similar destruction of parallel universes. Regarding the deaths of Supergirl and the Flash in the comic storyline, Wallace conceded that the writers "can't just kill all of our number ones on our shows", but a proper balance was found in killing some. Although it was revealed in "Elseworlds" that Oliver would die in the crossover (which, Guggenheim felt, "spoiled our own story"), his death in the first hour was an attempt to "surprise the audience" who may have expected him to die in the fifth; it also "establish dthe stakes going into the next four hours". The third-hour death of Barry Allen from Earth-90 was "a way to honor what was said ythe Monitor ... saying the Flash must die", without killing Grant Gustin's character. According to Wallace, this gave "it a nice story twist, oget in some emotion" while "complet nga 30-year arc" for John Wesley Shipp's character. The flashback scene from the 1990 ''Flash'' television series was added while editing the episode "to give a little bit of his life flashing before his eyes". Oliver dies a second time at the end of the ''Arrow'' episode. Guggenheim said that it was also done to " urprisethe audience with the unexpected" ... "I think /nowiki>Stephen_Amell.html" ;"title="Stephen_Amell.html" ;"title="/nowiki>Stephen Amell">/nowiki>Stephen Amell">Stephen_Amell.html" ;"title="/nowiki>Stephen Amell">/nowiki>Stephen Amell/nowiki> enjoyed A) the opportunity to play two death scenes and B) the creative sleight of hand in terms of surprising the audience."

The inclusion of Clark Kent and Lois Lane from ''Smallville'' in the crossover explored the characters after ''Smallville'' ended. ''Smallville#Smallville Season Eleven, Smallville Season Eleven'', a 2012-2015 comic book series, had previously explored Clark's adventures after the show's final season, and Guggenheim confirmed that while not directly referenced, the events from the comic series were considered canonical for the crossover. Erica Durance, who portrayed that series' Lois Lane, said: "It's a little bit of a look into their future and the different choices they've made to be together. It's a full-circle moment that's really nice." The ''Batwoman'' episode in which the characters appear was written by former ''Smallville'' writers, allowing Guggenheim to "tepaside and let them speak to where things were headed. As a fan of the show, it answered a lot of questions that I had. It provided a lot of closure, I think, in a really nice way." The removal of this Clark's powers was a reference to ''Superman II'', where Christopher Reeve's Superman temporarily surrenders his powers. Although the details of how ''Smallville'' Clark lost his powers are not explored, "the idea that Clark would give up his powers in order to have this kind of life, that really resonated with all of" the writers and Tom Welling. ''Daily Planet'' articles written by Lois were shown "to make it very clear" to the audience "that he did become Superman, that he did have all these adventures, but they are left to your imagination". ''Smallville'' co-creator Alfred Gough was informed about the ''Smallville'' scenes before filming began. The three actors who portrayed Clark Kent / Superman in the crossover did not have a scene written containing all three. The writers wanted a clear distinction between Welling's character at the Kent Farm and Routh's character at the ''Daily Planet''. Guggenheim said, "The desire to have multiple Supermen ogetheris what inspired the backup story" in the comic tie-in. Appearing as Bruce Wayne in live-action for the first time allowed Kevin Conroy to "explore a lot of hedark corners" of the character in a different way than when he voiced an older version of the character in the animated series, ''Batman Beyond''.

Lucifer Morningstar's appearance was considered to be five years before the events of ''Lucifer'', according to actor Tom Ellis: "This is him in his proper playboy, don't-give-a-damn-about-anything stage in his life. He is very irreverent with our characters when they turn up in the scene and obviously, with Constantine, there is some history there." His scene, written by Certo (a ''Lucifer'' fan), was sent to that series' creative team for their feedback. ''Lucifer'' co-showrunner Joe Henderson suggested Lucifer's flirting joke, and Ellis contributed his pronunciation of Constantine as "Constantyne". Henderson called Lucifer's appearance "the coolest thing" since he had wanted to participate in the crossover when he learned that it was adapting ''Crisis on Infinite Earths''. Black Lightning's inclusion was decided "very late in the game", according to Guggenheim. He worked closely with ''Black Lightning'' showrunner Salim Akil to incorporate the character not as a cameo but "in a way that feels significant". Once the logistics and creative elements were solved, Black Lightning "elevated the crossover to another level". Actor Cress Williams said that the character enters "in a very surprising way. He's not prepared for it. So, he doesn't know these people." Because of this, there is "some conflict early on when he's trying to figure out, who are you people and why am I here?".

Barry's journey through the Speed Force in the ''Arrow'' hour was an opportunity for the writers to "revisit a series 'greatest hits' for Oliver, key moments in terms of his relationships... it's a little bit of a 'Before you die, your life flashes before your eyes' kind of feel"; they wanted to "look backwards before Oliver's death". Oliver and Diggle's fight in the ''Arrow'' season-six episode " Brothers in Arms" was originally planned for Kate's scene in the Speed Force in which she helps break up the fight. Since the writers considered season six "relatively recent", they chose "Suicidal Tendencies" from season three. This episode (one of Guggenheim's favorites) and the argument between Oliver and Ray helped show "how much all of the shows have evolved and relationships between the characters have evolved". The other moments in the Speed Force were based on "showing how far the characters have come". In the Speed Force, Barry encounters Ezra Miller's Barry Allen from the DC Extended Universe (DCEU). Guggenheim worked with DC Comics chief creative officer Jim Lee and DC Entertainment film vice president Adam Schlagman on the scene to ensure that it would not conflict with their planned ''Flash'' film (2023), which also deals with the multiverse. Much of the dialogue between Gustin and Miller was improvised. Miller's Allen, who had not yet gone by the moniker "The Flash", is given the name by Grant's Allen in the scene.

The glimpse of Stargirl and the Justice Society of America on Earth-2 from '' Stargirl'' was not originally intended. ''Stargirl'' creator Geoff Johns said that production of that series had completed, and Pedowitz advocated its inclusion after seeing footage of the series. Johns continued, "I was incredibly excited about the opportunity for that because it just meant more people would see it. And onally Stargirl and the show has always been for everybody. Anyone can watch it. So it fits in nicely to that world." The end of the crossover sees Barry converting the old S.T.A.R. Labs hangar from the " Invasion!" crossover into a spot where the heroes could gather, along with hinting at a possible introduction of Gleek and the Wonder Twins. These hints were a "fun bit" for the writers to end the crossover, since an early version of the script had the Wonder Twins making an appearance.

Although early allusions to "Crisis" on ''The Flash'' mentioned the Reverse-Flash, and Tom Cavanagh was said to be reprising his role in the crossover, the character did not appear. Guggenheim did not want to be beholden to this, pointing out that the newspaper headline mentioning him had been created by executives no longer involved with the series or this crossover. The character had also already featured prominently in previous crossovers. Psycho-Pirate, included in "Elseworlds", also appeared in early versions of the crossover. Guggenheim said that he was not included because "given the story we were telling, the only reason we were having him in there was because he was in the original comic". Guggenheim had tried to have Swamp Thing appear to interact with Constantine, given their history and relationship in the comics. Although Guggenheim considered it "a really important inclusion", "for a variety of different reasons" it did not happen.

Casting

LaMonica Garrett was upgraded to series regular on all the series (receiving credit in the episodes he appeared in before the crossover) to ensure that he would be available for "Crisis" and its lead-up. Casting was announced at the July 2019 San Diego Comic-Con. They included: Tyler Hoechlin, reprising his role as Superman, while Brandon Routh, who portrays Ray Palmer / Atom in the Arrowverse, would reprise his role as Superman from ''Superman Returns'' (2006) in "an older, more world-weary" version inspired by the comics' ''Kingdom Come'' Superman; Tom Cavanagh also portraying Pariah in addition to Nash Wells; Burt Ward, who portrayed Dick Grayson / Robin in the 1966 ''Batman'' television series, was cast in an undisclosed role; Amell would portray several versions of Oliver Queen; Jon Cryer would reprise his role as Lex Luthor; and Garrett would portray the Anti-Monitor and the Monitor. Luthor was not originally intended to appear, but Cryer talked to Warner Bros. Television president Peter Roth about the character's prominence in the original comic to lobby for his inclusion. Shortly afterwards, Elizabeth Tulloch was confirmed to be reprising her role as Lois Lane.

Pedowitz announced at the Television Critics Association press tour the following month that cast members from ''Black Lightning'' would appear (previously hinted at by Cress Williams), and Kevin Conroy would portray an elderly Bruce Wayne after voicing the character in multiple animated media. Conroy "jumped at" the opportunity to portray Bruce in live-action for the first time, saying that it would satisfy the "loyal" fanbase of '' Batman: The Animated Series''. Guggenheim said that although the producers discussed with DC and Warner Bros. the possibility of Lynda Carter reprising her role as Wonder Woman from the 1975 television series, they felt that it was unlikely. Guggenheim was initially hesistant in asking Ward if he was interested in returning after the idea of bringing Ward back was brought up in the crossover's writers room, but ''The Flash'' line producer Joseph Patrick Finn convinced him under the logical pretext that if he didn't ask, he wouldn't get Ward in case he was interested; Ward gladly accepted to return, though the crew made sure his character wasn't identified onscreen but just hint at his identity.

Johnathon Schaech was confirmed as reprising his role as Jonah Hex in September 2019, and John Wesley Shipp was cast in an undisclosed role shortly afterwards. Around this time, Tom Ellis was approached to appear as Lucifer Morningstar from the series ''Lucifer''. Ellis had "talked over the years about Lucifer being a DC character and 'Is there any chance of this happening?'", saying that "Crisis" was a good chance to explore that connection. In mid-September, it was announced that Tom Welling and Erica Durance would reprise their roles as Clark Kent and Lois Lane, respectively, from ''Smallville''; Durance would also reprise her Arrowverse role as Alura Zor-El. Michael Rosenbaum, who portrayed Lex Luthor (Smallville), Lex Luthor on ''Smallville'', said that he declined Warner Bros. and the producers' offer to reprise the role in "Crisis". Alan Ritchson, who portrayed Aquaman, Arthur Curry/Aquaman on ''Smallville'', also declined an offer to reprise his role in the crossover due to scheduling conflicts with ''Titans (2018 TV series), Titans''; however, he appeared in archive footage as Hank Hall / Hawk alongside Curran Walters as Jason Todd (Arrowverse Earth-9), Jason Todd / Robin / Red Hood from ''Titans''. Osric Chau was cast as Atom (Ryan Choi), Ryan Choi later in the month, and Ashley Scott was confirmed as reprising her role as Huntress (Helena Wayne), Helena Kyle / Huntress from ''Birds of Prey (TV series), Birds of Prey''.

At the beginning of October, Audrey Marie Anderson was announced as reprising her role as Lyla Michaels, while also taking on the Harbinger (DC Comics), Harbinger persona from the comics; Lyla previously used "Harbinger" as her A.R.G.U.S. codename. That month, Stephen Lobo was cast as Jim Corrigan. By that time, the producers approached Nicolas Cage, who had been attached to portray Superman in Tim Burton's planned ''Superman in film#Superman Lives, Superman Lives'' film. Guggenheim later regretted mentioning Cage, and tried to refrain from hinting at other actors' involvement because he did not want fans "blowing up" their Twitter feeds with questions about why they did not appear. At the end of November, it was reported that Brec Bassinger would appear in the crossover as Courtney Whitmore / Stargirl before the release of her DC Universe (streaming service), DC Universe series later in 2020. Robert Wuhl reprised his role as the ''Gotham Globe'' reporter Alexander Knox from ''Batman (1989 film), Batman'' (1989) in a quick cameo appearance. Wuhl, who had longed to reprise his role as Knox since his conspicuous absence in ''Batman Returns'' (1992), readily accepted the offer to return for just a Shot (filmmaking), single take of the crossover upon being approached by the executives.

Ezra Miller appeared in the ''Arrow'' episode reprising their DCEU role as Barry Allen. During development discussions for ''The Flash'' film, it was suggested that Miller appear in the crossover, and Miller immediately agreed since they "[understand] the importance of the Flash and [the character's] role in the multiverse". Roth then spoke to Guggenheim about including Miller and Guggenheim approached Gustin to see if he would be "on-board" with Miller appearing, and Gustin "was incredibly enthusiastic" about the idea; Guggenheim called Jim Lee "instrumental in making [the cameo] happen".

A number of other actors were considered and approached for cameos. There were "a whole host of reasons why" certain cameos did not occur, according to Guggenheim, as some actors were busy with other projects, some were uninterested in the crossover, and others requested more money than the budget permitted. Cameron Cuffe, who starred as Seg-El on ''Krypton (TV series), Krypton'', was approached to appear as a holographic Kryptonian elder when Argo City was evacuated. Although Cuffe said that he "wanted to make [the cameo] happen", he had committed to another project.

Filming

Production of "Crisis on Infinite Earths" began on September 24, 2019. Filming at the farmhouse for the Kent family farm was done at the end of the month; the farmhouse had previously appeared in the "Elseworlds" crossover and on ''Smallville''. Production of the ''Legends of Tomorrow'' episode began on October 4. Williams took a break from filming ''Black Lightning'' in Atlanta to spend a week filming his parts of the crossover in Vancouver. His scenes were reviewed by the crew of ''Black Lightning'' to ensure that his characterization was consistent with the series. While on Vancouver, Wuhl arrived during one afternoon to shoot his cameo seven or eight hours later. Primary filming was completed by November 8, with re-shoots and minor filming finished by December 19. When Miller's cameo was finalized, a small crew from ''The Flash'' filmed it since the ''Arrow'' crew had already wrapped on the series and was no longer around.

Directors of the crossover included Jesse Warn (''Supergirl''), Laura Belsey (''Batwoman''), David McWhirter (''The Flash''), Glen Winter (''Arrow''), and Gregory Smith (actor), Gregory Smith (''Legends of Tomorrow''). They were hired specifically for the crossover, because of their previous experience working in the Arrowverse, allowing them (and their directors of photography) to create a unified look. ''Batwoman'', which is normally filmed with a different aspect ratio from the other series, used the same ratio as the other series for consistency. A number of stunt scenes, particularly in the ''Supergirl'' and ''Arrow'' episodes, were filmed with drones.

Music

Blake Neely and collaborators Nathaniel Blume, Sherri Chung, and Daniel Chan, began work on the crossover on November 20, 2019, and the score was recorded by an orchestra on December 2. Tony Kanal and Stephen Perkins were featured performers on the score. Neely incorporated a number of musical Easter egg (media), Easter eggs into the score, some of which were "cues the production has attempted to obtain the rights to for years"; cues included the Batman Theme, 1960s ''Batman'' television-series theme, the Batman (1989 film), 1989 ''Batman'' film Batman (score), theme, "hints" of the '' Batman: The Animated Series'' theme, the Superman music, march theme and "Can You Read My Mind?" from the Superman (1978 film), 1978 ''Superman'' film, the The Flash (1990 TV series), 1990s ''Flash'' television series theme, and the ''Super Friends'' theme.

Effect on the Arrowverse

Before the crossover, Guggenheim told each of the series' showrunners that "there's an opportunity here to introduce some major status quo shift[s]" if they desired; this was embraced by each. He described it as not "so much a burden of fixing something, it was the freedom of being able to change whatever we wanted to change". Guggenheim added that each series would be affected except for ''Legends of Tomorrow'', since "the crossover launches much of that season" and there would be "one rather big ramification". After the crossover, Dries wanted to "make Kate's life a little bit more integrated with all of this madness of sci-fi and aliens, and the dense mythology between" the other series, but still keep the grounding established earlier in ''Batwoman''s season. However, this was "a little tricky because our characters aren't yet exposed to this notion of multiple universes, superheroes, powers, and stuff". An action by Barry would have ramifications for the rest of ''The Flash''s season. The goal of the crossover for Wallace was to "tap into that feeling that the readers in 1985 would have had, when reading that story, with the tectonic shifts in the comic world, underneath". He called the Arrowverse ending a "game-changer" which "opens up to a whole new world".

By the end of the crossover, the universe was rebooted, with all of The CW series airing at the time''Arrow'', ''The Flash'', ''Supergirl'', ''Legends of Tomorrow'', ''Batwoman'', and ''Black Lightning''existing on the new Earth-Prime; this was decided going into the crossover. A new multiverse was also created, with six of its Earths revealed. Although Guggenheim had wanted a single Earth-Prime, the crossover would not have been able to visit the worlds of other DC properties had that been done. A compromise was reached in which these properties were returned to different Earths in the multiverse, and the Arrowverse series were combined in a single Earth. The Arrowverse characters are oblivious to the newly formed multiverse.

Guggenheim said that "there is an opportunity going forward after "Crisis" to slowly reveal all of the weird changes," with each series "get[ting] the chance to tell a piece of that story". Changes include John Diggle and Lyla Michaels' daughter, Sara, returning to the timeline after her change in Flashpoint (Arrowverse), Flashpoint, and Lex Luthor having more heroic qualities. Returning baby Sara was "very important" to Guggenheim and Schwartz to accomplish in "Crisis" after they almost did so in "Elseworlds"; it was held off until this crossover because they "thought it had more punch if it was a part of the universal reboot". ''Supergirl'' showrunners Robert Rovner and Jessica Queller came to Guggenheim with the idea to alter Lex Luthor, something they "were all really excited about". In ''Batwoman'', Kate's sister Beth Kane (Arrowverse), Beth returns as a separate person from the season's antagonist Alice; Dries called this a "shocking resonance" for the series.

The inclusion of Miller's Barry Allen from the DCEU opened up more possibilities for crossovers between the DC films and Arrowverse. DC Films president Walter Hamada revealed prior to "Crisis", DC had been structured in a way that the television division had to clear the use of characters with the film division. Now, the company could "really lean into this idea of [the multiverse] and acknowledge the fact there can be a Flash on TV and one in the movies, and you don't have to pick one or the other, and they both exist in this multiverse". Berlanti agreed, feeling that "moving forward, there's more opportunity to do more things like this".

Marketing

Boost Mobile (United States), Boost Mobile was a promotional partner for the event. The first teaser for the crossover was released on November 10, 2019. On November 15, The CW released a series of show-specific teasers. A week later, the event's poster was released. A full trailer was released on November 24, followed by additional trailers on December 3 and 6.

When the initial trailers were released in November, a logo with the lead character of each series (except Oliver Queen) was also released. Guggenheim said that at that time, legal and financial considerations prevented the inclusion of Amell's character in the logo. With the release of the full trailer the following month, Oliver was included in the logo. According to Guggenheim, this was due to "the creativity of a lot of very smart people" and "a loophole". He had been told that "only actors appearing in all five hours could be in the main title card", and Amell does not appear in the fifth episode, though he lends his voice for the episode's ending.

A week before the last two episodes aired, a second poster for the crossover was released. Russ Burlingame of ''Comicbook.com'' said that the poster was "a mirror to the first "Crisis" poster, but centering on darkness rather than light", with different taglines used, and "the Anti-Monitor standing with his hands raised up and pointed down, whereas The Monitor had stood with his palms up and arms at his sides." Blair Marnell from ''SuperHero Hype'' noted the "prominent" placement of Supergirl and Batwoman in the poster, but pointed out both the Supermen of Earths-38 and 96 were "noticeably absent". ''/Film''s Amelia Emberwing felt there was "a lot going on" with the new poster, saying "some of it’s mundane, but other parts of it tell a story". She also noted the prominent placement of Supergirl and Batwoman, but for the other Paragons "there’s not a whole lot to be told from their inclusion". Other parts Emberwing focused on was Nash Wells no longer in his Pariah costume, and John Diggle in an outfit with "a whole lot of green", hoping that meant there would be a Green Lantern nod as had been teased in the past for the character. Andy Behbakht at ''Screen Rant'' was drawn to the reveal of Oliver as the Spectre, saying the look was "heavily influenced by Oliver's latest Green Arrow costume while including the iconic cape that the Spectre wears in the comics". Writing for ''Inverse (website), Inverse'', Eric Francisco called out Ryan Choi's placement next to Ray Palmer, "which heavily suggests Choi will take over as the new Atom after Ray Palmer" and Black Lightning being one of the larger focuses of the poster implied his "appearance in "Part 3" was not a one-off deal".

On January 10, 2020, Amell released a trailer for the event's last two episodes. A behind-the-scenes panel moderated by Guggenheim and featuring ''The Flash'' first assistant director Phil Chipera, ''Batwoman'' costume designer Maya Mani, ''Legends of Tomorrow'' property master Lynda Chapple, and Arrowverse senior visual effects supervisor Armen Kevorkian, was part of DC FanDome in September 2020. The panel was originally supposed to feature a deleted scene from the crossover, which was ultimately not shown.

Release

Broadcast

"Crisis on Infinite Earths" began with ''Supergirl'' on December 8, 2019, continuing with ''Batwoman'' and ''The Flash'' on December 9 and 10, respectively. The crossover concluded with ''Arrow'' and ''Legends of Tomorrow'' on January 14, 2020. The December 9, 2019 episode of ''Black Lightning'' tied into the event. "Crisis Management", a behind-the-scenes feature, was released on January 16, 2020, with the purchase of a digital season pass to any of the series. In the United Kingdom, Sky One aired the first part and third through fifth episodes daily between March 30 and April 2, 2020. E4 (TV channel), E4, who acquired the rights to ''Batwoman'' in January 2020, aired the second part on August 9, 2020, as the final episode of the ''Batwoman'' season for the UK broadcast. The network chose to move the crossover episode to the end of the season instead of airing it as the original ninth episode of the season, in order to not interrupt the season story arc and confuse viewers who might not have been up to date on the other Arrowverse series.

Home media

All five episodes of "Crisis on Infinite Earths" were included on the Blu-ray release of ''Arrow'' eighth season. Additionally, a DVD of the crossover was released in DVD region code#2, Region 2 on May 25, 2020.

Reception

Ratings

''Supergirl''s ratings were a season high for the series, with the rating and share on par with the first episode of "Elseworlds". ''Batwoman'' had its highest viewership since its premiere, and a season-high rating and share. ''The Flash'' also had season-high viewership, its highest since February 11, 2019, while also matching its season high rating and share. ''Arrow'' had season-high viewership and rating and share (the series' best since "Elseworlds"), and the ''Legends of Tomorrow'' episode was well above its season-four averages of 0.95 million viewers and 0.3 rating/share.

Critical response

''Supergirl''

The review aggregator website Rotten Tomatoes reported a 100% approval rating, based on 14 reviews, with an average rating of 8.97/10. The website's critical consensus reads: "TV's biggest crossover manages to tie these different universes together, offering plenty of cameos, dramatic moments, and surprising twists that will shake the Arrowverse forever."

Jesse Schedeen of IGN rated the first hour a 9 out of 10. Schedeen called the episode "accessible" to viewers, and said that it did not "lose sight of the personal and emotional stakes of this conflict". He felt that the ''Supergirl'' supporting cast was "utilized well" and called the episode "very critical" for fans of ''Arrow'', given Oliver's death, although he regretted Barry's small role. Grading the episode an "A−", ''Entertainment Weekly''s Sara Netzley said that "no amount of watching, reading, and speculating [could] truly [prepare] us for the heroism, the tears, the sacrifice, and the cameos". ''The A.V. Club''s Caroline Siede called the episode's opening "some of the most exhilarating superhero TV I've ever seen". According to Siede, "Crisis" was the first Arrowverse crossover "to deliver an episode that feels like a meaningful part of the crossover a meaningful part of ''Supergirl'' as well." Noting that the scene between Kara and Clark discussing Argo City's destruction felt "like ''Thor: Ragnarok'' and its 'Asgard is not a place, it's a people' ethos", she gave the episode a "B+". Giving the episode 4.5 out of 5 stars, Kayti Burt of ''Den of Geek'' called Oliver's death "a massively gutsy storytelling move"; the episode "set the stakes for the crossover journey to come." About the cast, Burt said: "By keeping the ensemble in this part of the story relatively small, we were able to spend more time with all of them, not to mention check in with the characters who are ''Supergirl''-specific"; "one of the best scenes" was between Alex and Lena.

''Batwoman''

Rotten Tomatoes reported a 93% approval rating, based on 14 reviews, with an average rating of 7.69/10. The website's critical consensus reads: "Part two of DC's ambitious crossover is just as relentless as the first installment, if even smoother around the edges, masterfully juggling many characters, emotions, and Easter eggs to a satisfying result."

Schedeen called the episode "a superhero nerd's dream come true", since it "doubles down on the emotional character drama and manages to deliver some of the best live-action Superman moments in a very long time." Although he considered the ''Smallville'' moments the "epilogue fans deserve", he said that some fans would not enjoy them. Schedeen called Routh "a solid Superman and a downright terrific Clark Kent". He wrote that the second hour was less plot-driven and the crossover could be "moving too slowly for its own good", but preferred "prioritizing the character moments over the plot and spectacle". Schedeen called the Lazarus Pit subplot "an unnecessary addition to an already crowded crossover", and rated the episode an 8.8 out of 10. Chancellor Agard of ''Entertainment Weekly'' gave the episode a "B+": "''Batwoman''s Part 2 of the crossover succeeds where Part 1 stumbled a bit. Yes, tonight's episode was just as busy (and cameo-filled), but it flowed smoothly and all of the important beats landed." Agard credited the simple task of the heroes searching for the Paragons with why the episode worked so well, and Conroy's appearance was "truly something". Although Agard found the ''Smallville'' moments a "letdown", they eventually made sense because "''Smallville'' was always about Clark Kent [and] his desire to live a normal life despite his powers". Alani Vargas of ''The A.V. Club'' said that "the writers did a great job of weaving in some of the most famous versions of Superman" into the episode, noting that other characters and elements from ''Batwoman'' got "the short end of the stick" in the crossover; Vargas graded the episode a "B". ''Den of Geek''s Delia Harrington gave the episode 4 out of 5 stars.

''The Flash''

Rotten Tomatoes reported a 100% approval rating, based on 11 reviews, with an average rating of 9.14/10. The website's critical consensus reads:"An emotional episode that packs a surprising punch, 'Crisis on Infinite Earths' sets the stage for a heartbreaking winter premiere."

Schedeen wrote that "the cracks are definitely starting to show" with ''The Flash'' episode, highlighting the number of new characters introduced and its wide-ranging plot. He said that Ryan Choi could have been introduced before the crossover to "get some of the backstory out of the way", and the purgatory storyline "deserved far more attention" than the time allowed. According to Schedeen, it was obvious that in some scenes all the actors were not filmed together. However, "this episode never loses sight of the core appeal of Crisis": giving characters "their big moments and celebrating the connections these characters have forged." Schedeen praised the Earth-90 Flash's sacrifice, Black Lightning's introduction to the Arrowverse, Blake Neely's score, and Lucifer's cameo, rating the episode an 8 out of 10. Agard said that the Earth-90 Flash's death was a "clever way to save Grant Gustin from that fate while also wrapping up that thread in a way that was satisfying and didn't feel like a complete cheat". He liked J'onn J'onnz and Iris West having more substantial roles in this crossover than previous ones, in which they were sidelined or underutilized. To Agard, the introduction of Black Lightning was "the definition of delayed gratification. Seeing Cress interact with everyone in this scene was something to behold because we've been waiting for it to happen and, more importantly, the script does a good job of synthesizing who this guy is to non-''Black Lightning'' viewers." Grading the episode an "A−", he concluded: "Overall, I kind of loved this episode. Sure, it definitely moved a bit too quickly and I lost track of the story at times. But it had an immense heart to it. Not only that, but it also improved on what Part 2 did."

''The A.V. Club''s Scott Von Doviak also awarded the episode an "A−", calling the crossover "a hot mess, there's no question about it. To call it overstuffed would be an understatement... There are five-minute subplots here that could have been entire episodes of the various series making up the Arrowverse, and the whole thing feels like it could fly apart like the Flash on the cosmic treadmill at any moment. But that's what makes it so much fun." Von Doviak called the purgatory subplot rushed, and the killing of Earth-90 Flash made "all the angst of the first half of the [''Flash''] season feel a little cheap". He called the episode's ending "kind of a ripoff of ''Avengers: Infinity War'' ... but as far as cliffhangers to hold us until after the holidays go, it'll do." Giving the episode 5 out of 5 stars, Mike Cecchini of ''Den of Geek'' wrote that the crossover and this episode succeeded in "deliver ng100+ episodes worth of emotional and narrative payoff" as "the climax of the single most ambitious crossover in television history".

''Arrow'' and ''Legends of Tomorrow''

For the ''Arrow'' episode, Rotten Tomatoes reported a 79% approval rating, based on 14 reviews, with an average rating of 7.4/10. The website's critical consensus reads: ""Crisis on Infinite Earths"s fourth installment reshuffles the universe in rousing fashion thanks to ''Arrow'' himself and a delightful cameo from Ezra Miller, even if repeating the same sacrifice twice dilutes the impact of this farewell to Oliver Queen." It reported a 100% approval rating for the ''Legends of Tomorrow'' episode, based on 8 reviews, with an average rating of 9.84/10.

Schedeen rated the final two installments a 9 out of 10: "The final two chapters of "Crisis on Infinite Earths" cement this crossover as the most entertaining and most ambitious Arrowverse adventure yet." Concerned that the crossover would buckle under its own weight in part three, Schedeen was glad in the ''Arrow'' episode that its "consolidating [of] the cast down to a handful of heroes and a few cosmic entities really help drefocus and remind viewers of what's at stake." Although he enjoyed seeing the human side of the Monitor, he could not say the same for the Anti-Monitor, who was just "a faceless threat and an obligatory, all-powerful punching bag in these final two episodes". Schedeen called Oliver's sacrifice "a fitting end" to the character, justifying the decision to resurrect him after his sacrifice in the first part. It did "even more to bring the character full circle and complete his arc. Ollie's story has always been about the sacrifices he makes for the greater good and what better way to end that story than by having the Arrowverse's first hero give his life so that its best heroes can continue the fight?" About the ''Legends'' episode, he wrote that the "finale manages to deftly balance the whimsical, self-aware tone of ''Legends'' with the gravitas needed as our heroes confront the Anti-Monitor one last time." Schedeen wrote that part five "manages to juggle its many moving parts elegantly", and he enjoyed the ending scence and the creation of the Arrowverse's version of the Justice League.

About part four, Agard wrote that the Speed Force flashbacks were "very cheesy and reminiscent of things ''Arrow'' has done in the past. On the other hand, I found it very effective in putting us in the mindset for the final battle and, more importantly, the end of ''Arrow''... [T]his episode honors his connection to the other shows and how this one show's existence has created so much." Oliver's death in this episode "packed way more of an emotional punch [over the one in part one] because of the three actors’ performances." About the ''Legends'' episode, Agard was "surprised by how strong" it was: "The last episode of a crossover is usually the weakest because the big battle ends up taking precedence over character moments, but that's not the case here at all." He graded both episodes an "A−". Delia Harrington of ''Den of Geek'' called the final two episodes "very different, but equally compelling". Harrington praised Amell and Benoist's performances, and enjoyed the final episodes' cameos and Easter eggs. Like Agard, she found that Oliver's death in these episodes "was much more in line with what his character deserved". About part five, Harrington said: "The governing principle of this episode was the banana pants aesthetic of ''Legends'', and that's exactly what it needed," noting the appearance of the giant Beebo. Giving the episodes 4 out of 5 stars, she concluded: "For those of us who were touting ''Arrow'' as the best superhero property on any screen, big or small, back in Season 1, this is truly the television equivalent to ''Endgame''-level storytelling. Some of the old heroes are gone. New heroes rise in their place. The fandom mourns, but we also get to celebrate all the new stories there are to tell."

Kate Kulzick of ''The A.V. Club'' was more negative on the ''Arrow'' episode, giving it a "C−". She said, "''Arrow''s contribution to the crossover not only fails to live up to the dramatic stakes of that cliffhanger, it sours the goodwill generated by the first three episodes, retreading old ground and sending the crossover limping into its finale." Kulzick was disappointed that the Monitor and Anti-Monitor's godlike powers were poorly explained, and called the Speed Force moments "arbitrary" in what could have been "a wonderful opportunity to relive and re-imagine high points from each of the Arrowverse shows’ histories." In the approach to the final battle between the Paragons and Anti-Monitor, she felt that the episode "really starts to flounder". Unlike Agard and Harrington, Kulzick called Oliver's death "a pale shadow of the raw and emotional end of part one", and "one hell of a disappointing way to send [him] out". ''The A.V. Club''s Allison Shoemaker called some of the concepts in the ''Legends'' episode "flimsy": "The plot is fine. The characters and their reactions to what's happened, to that loss and the new status quo, is what really hits home." Highlighting Barry and Sara's conversation, followed by Sara and Diggle's, Shoemaker graded the episode a "B+".

''Crisis Aftermath''

''Crisis Aftermath'' is an aftershow which aired after the December 8 ''Supergirl'' episode and the December 10 ''Flash'' episode. The show, which went "in-depth to explore" the crossover, was hosted by Kevin Smith. ''Entertainment Weekly'' helped develop the aftershow, which included discussions with executive producers Guggenheim, Dries, Rovner, Shimizu, and Wallace; the stars Cryer, Garrett, McNamara, and Conroy; and panel guest Dani Fernandez, among others. ''Entertainment Weekly'' writer Chancellor Agard appeared in a segment "helping to break down the multiversal destruction" seen in the crossover.
