Santa Claus Conquers the Martians is a cyberpunk movie.

Mars is a dystopian, broken society in which cyberware is so ubiquitous that we only ever see one Martian without visible augmentation. Every character in the movie does what they do for purely selfish reasons, with the exception of the idiot Droppo, the old man Chochem who remembers society for what it was before it went to hell, and the mythological embodiment of generosity himself. When Chochem suggests that Mars needs a Santa Claus, the immediate response isn't to research and emulate St. Nick, nope. Martian society is so degenerate that the first idea is to commit a crime: to kidnap the jolly old elf. And all of Earth's governments are incapable of stopping them.

Cyberware, broken society, selfish characters, rampant crime, laughably inadequate government? What genre does that sound like?

When I pointed out that Santa Claus Conquers the Martians predates Blade Runner, the film that most people consider to be the first cyberpunk movie, by some 18 years, at a tabletop session of Cyberpunk 2020, I was less than popular with those assembled.

I decided to not press my luck by pointing out that it came out 4 years before the book Do Androids Dream of Electric Sheep.

Hooray for Santy Claus.
