Santa Claus Conquers The Martians (1964)

Producer Joseph E. Levine's masterpiece. The more astute of you may have realised by now the Martians are devoid of their usual weaponry: Tripods, death rays, etc. They must have all been in the shop when they kidnapped Santa. In fact, as Martians go, they're sort of puny and whiny, not so much warriors as bureaucrats, really. That's why they've held off invading Earth, they know they'd be in awash of liability claims. And we can see some not-so-subtle propaganda here. The socialistic Martians have lost the ability to have fun, so they need Santa to show them a good time, like the capitalist whore he is.
