Hello, everyone I am looking for some leftist films from non-socialist countries as part of my research on the international Communist movement, thank you for your help. Here are a few I've seen and I think they're good：
O Lucky Man! 1973
Another Country 1984 (Based on real history, story of Guy Burgess one of the Cambridge Five)
Good bye, Lenin! 2003（Not exactly a leftist movie, but worth watching）
Léon Morin, prêtre 1961
About Salo or 120 days of sodom, I've seen it. I was gonna include it, but it's gross. I would be very sorry if someone actually went to see the movie through this post and was scared. Thanks for the other suggestions! By the way, Pier Paolo Pasolini‘s other movies are worth watching, too. As far as I know, he was a ML.
