To be honest the only movies I have seen with Cazale is the GF's and Dog Day Afternoon. Yes, I do believe he was a very good actor. It's possible I have seen other movies with him in it, and didn't realize it. Can you name a couple more that I may have seen? I don't really know anything about him except for those two movies.
I almost forgot about the Deer Hunter it's been so long since I saw it. He was excellent in there too. The only other film of his I saw was The GF. He played Fredo superbly tho, you could actually believe he was Fredo all weak and stupid
I totally agree. He is a talented actor and would have gone a long way. I highly recommend Deer Hunter and Dog Day Afternoon (he plays a weak character as well) Beth . Both films have powerful acting and a good storyline.
