Santa Claus Conquers the Martians is a 1964 American science fiction comedy film directed by Nicholas Webster, produced and written by Paul L. Jacobson, based on a story by Glenville Mareth, that stars John Call as Santa Claus. It also features an eleven-year-old Pia Zadora as Girmar, one of the Martian children.

Plot
The Martians Momar (“Mom Martian”) and Kimar (“King Martian”) are worried that their children Girmar (“Girl Martian”) and Bomar (“Boy Martian”) are watching too much Earth television, most notably station KID-TV’s interview with Santa Claus in his workshop at Earth’s North Pole.

Consulting the ancient 800-year-old Martian sage Chochem (a Yiddish/Hebrew word meaning “sage”, though pronounced differently from the film’s version), they are advised that the children of Mars are growing distracted due to the society’s overly rigid structure. From infancy, all their education is fed into their brains through machines and they are not allowed individuality or freedom of thought.

Chochem notes that he had seen this coming “for centuries”, and says that the only way to help the children is to allow them their freedom and be allowed to have fun. To do this, Mars needs a Santa Claus figure, like on Earth. Leaving Chochem’s cave, the Martian leaders decide to abduct Santa Claus from Earth and bring him to Mars.

The Martians cannot distinguish between all the fake Santas, so they kidnap two children to find the real one. Once this is accomplished, one Martian, Voldar, who strongly disagrees with the idea, repeatedly tries to kill Santa Claus along with the two kidnapped Earth children. He believes that Santa is corrupting the children of Mars and turning them away from Mars’ original glory.

When they arrive on Mars, Santa and the children build a factory to make toys for the Martian children. However, Voldar and his assistants, Stobo and Shim, sabotage the factory and change its programming so that it makes the toys incorrectly. Meanwhile, Dropo, Kimar’s assistant, who has taken a great liking to Santa Claus and Christmas, puts on one of Santa’s spare suits and starts acting like Santa Claus. He goes to the toy factory to make toys, but Voldar mistakes him for Santa and kidnaps him.

When Santa and the children come back to the factory to make more toys, they discover that someone has tampered with the machines. Voldar and Stobo come back to the factory to make a deal with Kimar, but when they see the real Santa Claus, they realize that their plan has been foiled. Dropo, held hostage in a cave, tricks his guard Shim and escapes. Kimar then arrests Voldar, Stobo, and Shim. Santa notices that Dropo acts like him, and says that Dropo would make a good Martian Santa Claus. Kimar agrees and sends Santa and the children back to Earth.
