If you haven't read his memoir you definitely should, it's a well written piece where he reflects on his life, what he did wrong, what he did right, and the joy and pain that followed him through it all. He was a flawed man, but he was a good man. He will be deeply missed.
Edit: Oh man, I can't believe I'm crying at work over an actor.
I did too! I don't think I've cried over a Hollywood death until now. Maybe Robin Williams but can't remember.
I highly recommend the audio book, he reads it himself.
