UN CHIEN ANDALOU (1929)

Probably the best known surrealist avant garde movie, co-created by none other than Salvador Dalí. He wanted it to piss everyone off, and was annoyed that people seemed to like it.

THE BROADWAY MELODY (1929)

The first of our forgotten best picture winners was such an early sound movie that it is hard to watch, even if it is considered one of the very first movie musicals.
