There’s also a curious little film from 1945 that famed radio-writer Arch Oboler wrote and directed, entitled “Strange Holiday,” in which an ordinary, middle-class guy comes back from a fishing vacation to find America has been taken over by totalitarian invaders. Gets put in a prison camp and everything. It’s a bit low-budget and somewhat unsubtle, even though Oboler did manage to cast a big name like Claude Rains in the lead.
Generally not too well-known a film, and hasn’t tended to circulate all that much. But interesting as an oddity.
I’d like to see that. Not at my library or on netflix though.
