If you liked it, you could try Carpenter's first movie Dark Star, written by the guy who wrote Alien. It's a low budget space comedy with a bomb that can talk. The film is 20 minutes longer than it should be in the middle, because distributors required an extra segment for runtime sakes, but it's so charming that I don't mind.

I'll also recommend Playtime by Jacque Tati, if you enjoyed Sellers' physical acting in Dr Strangelove. It's a satire of the modern metropolis. Kind of a sophisticated french Mr Bean.

Ooh! And 'Songs From The Second Floor' by Roy Anderson. Its a series of absurdist vignettes in a hollowed out dystopia. Very funny if you're into that sort of thing - weird political satire that is. There's a good bit about a revered military commander waking up from a coma and immediately heiling Hitler, for example.

The Discreet Charm of the Bourgeousie is also fun. It's a surrealist satire of... the bourgeousie, told through a number of dreams within dreams. It's pretty interesting but to be honest I wanted to enjoy it more than I actually did. Still, funny enough. I'll rewatch it at some point I would imagine.

I could go forever to be honest. I love movies that make no real attempt at realism. Kin Dza Dza for example... Soviet era low budget sci fi satire. There I go again.
