Hello everyone!
I apologize if you have gotten this question before and if you have just posting a link will be helpful but my question w/background info is:

This summer i am planning on having a movie month to watch a bunch of classics and basically to catch up with the rest of the world. I always get "WHAT! you haven't seen ___ movie!" A LOT! So what movies, especially from an actor's point of view, do you find important and fun to watch?
