Considered by many to be one of the worst movies ever made, this has become a cult favorite. The plot involves the people of Mars, who decide to kidnap Santa Claus from Earth and bring him back to Mars, in order to help Martian children learn how to regain their individuality and freedom of thought, and in general just be children. (Note an eight-year-old Pia Zadora playing the role of one of the Martian children.) This movie is now in the public domain, and may be watched for free on various Internet sites.
