As our faithful chronicler informs, the sci-fi comedy (self-descriped as “yuletide science fiction fantasy” and hoped to find a niche for a perceived market gap) by Nicholas Webster and Paul L. Jacobson, Santa Claus Conquers the Martians—universally panned though significantly debuting the figure of Mrs Claus a full three weeks before appearing on the Rankin and Bass (previously) television special Rudolph the Red Nosed Reindeer, premiered in cinemas on this day in 1964. It was to receive the Mystery Science Theatre 3000 treatment on 21 December 1991—shortly after MST3K was syndicated by the Comedy Central cable network and thus solidifying its enduring popularity aside from making the movie a cult classic. A young Pia Zadora has her film debut as Girmar—the Martian Girl.
