Moon Zero Two is a 1969 British science fiction film from Hammer Films, produced by Michael Carreras, directed by Roy Ward Baker, that stars James Olson, Catherine Schell, Warren Mitchell, and Adrienne Corri.
Moon Zero Two was filmed at the ABPC Elstree Studios in Hertfordshire, England. The screenplay was by Michael Carreras from an original story by Gavin Lyall, Frank Hardman, and Martin Davison. The film was billed on its U.S. film poster as a space Western with the phrase 'The first moon "western"...'
In the year 2021, the moon is in the process of being colonized, and this new frontier is attracting a diverse human population to lunar settlements like Moon City, Farside 5, and others.
Two denizens of this rough-and-tumble lunar society are the notorious millionaire J. J. Hubbard and former-astronaut-turned-satellite-salvager Bill Kemp, the first man to set foot on Mars. He left Space Corporation because he wants to explore space, while his former employer only wants to operate commercial passenger flights to and from Mars and Venus.
When Hubbard hears about a small 6000-tonne asteroid made of pure "ceramic" sapphire that is in a low lunar orbit, he hires Kemp to capture it with Kemp's old "Moon 02" space ferry. Kemp is to transport it down to the surface of the lunar farside, even though doing so would be against Space Corporation law. Kemp, however, has little choice because he learns from Hubbard that his flight license will soon be revoked due to protests from Space Corporation. Hubbard also reveals that he plans to use the giant sapphire for building much improved rocket engine thermal insulators, profiting from the need for even more powerful rockets to colonize Mercury and the moons of Jupiter.
A young woman named Clementine arrives looking for her brother, a miner working a distant patch of moonscape at Spectacle Crater on the lunar farside. Unfortunately, the trip from Moon City on the nearside would take six days by a lunar vehicle. Since Kemp can go there much more quickly using Moon 02, she convinces him to help her learn if her brother is still alive. The terrain around his camp is not suitable, so Kemp and Clementine land and travel the remaining distance using a lunar buggy. The two discover that Clementine's brother is dead, and that he was murdered for his discovery: a large vein of nickel that would have made him a rich man. They are shot at by some of Hubbard's men, who have followed them to the camp.
Hubbard was unhappy to learn that Kemp was leaving to assist Clementine, because he was responsible for the brother's death. Hubbard needed the claim to be abandoned, so he could to take control of it and use it as the isolated landing site for the sapphire asteroid. Clementine's brother would never have left after discovering the nickel vein. Hubbard blackmails Kemp into completing the asteroid job by threatening his and Clementine's lives, but in the process, Kemp kills the millionaire in a shoot out. Because Clementine is her brother's next of kin, Kemp tells her that she now has legal ownership of the nickel vein and soon the "crashed" sapphire asteroid, making her a very wealthy woman.
Special visual effects for the film were created by a team headed by veteran visual effects artist Les Bowie, who worked on numerous Hammer productions and several notable British-made science fiction features.
The "Moon 02" Spacecraft in the film is described as being 'quite old'.
A dialogue reference to Neil Armstrong becoming the first man on the moon was inserted, and a lunar monument erected on the landing site was added to the production. The film was released three months after the Apollo 11 moon landing.
