Santa Claus Conquers the MartiansSanta Claus Conquers the Martians is a 1964 science fiction movie that regularly appears on lists of the all-time worst movies ever made. It is regularly featured in the "bottom 100" list on the Internet Movie Database. It was directed by Nicholas Webster, and it stars John Call as Santa Claus. It also includes an 8-year-old Pia Zadora playing the role of one of the Martian children.
The story involves the denizens of the planet Mars, who are worried that their children are watching too much television. Following the advice of a Martian sage or wise elder (or something), the Martians kidnap Santa Claus from Earth and bring him to Mars to make toys for the children of their planet. One warmongering Martian rebels and tries to destroy Santa Claus, as he believes that Santa is corrupting the children of Mars and turning them away from the original glory that Mars used to have.
The movie is also the title (and the subject) of one of the most popular episodes of Mystery Science Theater 3000. In addition to original host Joel Robinson and his robot friends giving the movie a much-deserved vivisection with their wisecracks, the TV episode also includes the MST3k comedy segments "The Wish-Squisher" and "A Patrick Swayze Christmas."
