Santa Claus Conquers The Martians (1964) on Tubi
This is what my brothers and I consider the weirdest Christmas movie of all time.
It’s has some three stooges comedy, children working longing to work the factory, and a delightfully festive and unhinged plot, and is a scathing review of what the 1960’s thought the future could be.
P.S. There’s also a Rifftrax version which I have not seen.
P.P.S the movie is in the public domain!
My sister and I used to watch this all the time, not even just during Christmas. It was so weird. Haven’t seen it in years, I’ll have to give it another watch!
