Pia Zadora In A Science Fiction Movie For Families (1964) One of the worst (and best!) movies ever made, Santa Claus Conquers the Martians blasts Old Saint Nick into space to deal with grumpy aliens! Oozing campy fun, this film is a celebration of ridiculous costumes, cheap sixties sets, and absurd dialogue. But unlike other classic “bad” films like Killer Clowns from Outer Space, Santa Claus Conquers the Martians succeeds as a family film with its wholesome themes and loveable characters. The Martians are more “grumpy” than evil, and many of them are sympathetic. Santa Claus Conquers the Martians truly is fun for the entire family: the kids are wrapped up in a story with Santa and space, and the adults laugh themselves silly.
