Santa Claus Conquers the Martians is a 1964 science fiction film directed by Nicholas Webster and starring John Call as Santa Claus. Martians need a Santa Claus figure, like on Earth, so the Martian leaders decide to abduct Santa Claus from Earth and bring him to Mars.

As the Martians cannot distinguish between all the fakes Santas, they kidnap two children to find the real one. However, one Martian, Voldar, who strongly disagrees with the idea, repeatedly tries to kill Santa Claus along with two kidnapped Earth children, as he believes that Santa is corrupting the children of Mars and turning them away from the race’s original glory.
