I'd have to say the "Boondock Saints". It's just so funny, yet no one I've talked to has ever heard of it. Another would be "The Hitchhikers Guide To The Galaxy".
Boondock Saints has the FUNNIEST lines. "How the f***... what the f***... how the f*** did you two f***in' f***s... F***!" "Well, that certainly illustrates the diversity of the word."
People hated the Hitchhiker's Guide movie, but I rather enjoyed it. It didn't follow the first book, precisely, and added the gun, but the cast was brilliant (Alan Rickman as the voice of Marvin the Paranoid Android), the ship was freaking awesome, and "So Long And Thanks For All The Fish" was insanely catchy in my head.
I have to add Sukiyaki Western Django to this list. It was SO weird and confusing but the whole thing was done in this beautiful style, and the Heike and Genji gangs were so funny. Too bad almost NO ONE has ever heard of it.
Oh, and Suicide Club. It's a stylistic Japanese thriller that explores the dissatisfaction and dissociation of modern Japanese youth in this really neat and compelling way, but again, no one has ever heard of it.
