X-Men (film series)

X-Men is an American superherofilm series based on the X-Men, a group of characters created by Stan Lee and Jack Kirby for comic books published by Marvel Comics. Encompassing thirteen live-action films, it was produced by 20th Century Fox and Marvel Entertainment from 2000 to 2020.

Throughout the 1980s, Marvel embarked on efforts to create film versions of the X-Men stories. After prolonged development, Fox purchased rights in 1993 and developed a trilogy comprising X-Men (2000), X2 (2003), and X-Men: The Last Stand (2006). A succession of films followed, expanding the fictional universe. Plans for a reboot led to the production of four prequel films chronicling the X-Men as young people, from X-Men: First Class (2011) to Dark Phoenix (2019). From 2009 to 2020, Fox oversaw the creation of another six films as X-Menspinoffs, which feature Wolverine, Deadpool, and the New Mutants. The studio's television networks division produced Legion and The Gifted (both 2017–2019) tangential to the films. Fox controlled the production of X-Men films until its acquisition by The Walt Disney Company in 2019, effectively terminating all planned adaptations from the studio.

Critical opinion about X-Men films differ significantly. Most average at least moderately positive scores on Metacritic and Rotten Tomatoes, but a disparity exists between the best-reviewed entries, X-Men: Days of Future Past (2014) and Logan (2017), and the worst, X-Men Origins: Wolverine (2009), Dark Phoenix, and The New Mutants (2020). At the box office, the films are generally successful and constitute one of the highest-grossing film franchises of all time, grossing over $6billion worldwide.
