As the actor-director celebrates his 65th birthday on 28 November, 2015, here are some of his most memorable quotes.

You can't betray yourself too often, or you become somebody else.

You get three hours' sleep and then you start all over again. Relentless. Pre-production was almost harder than filming. I was all over the city every day. It was really exhausting.

Pollock said several times that he couldn't separate himself from his art. Not knowing much about modern art when I began to read about him, I was much more his persona - his struggles as a human being - that was interesting to me.

There's always a reaction based on fear. People assume if you're criticising a decision to go to war, then you're saying something against the soldiers-which is not the case.

You can mostly forget ethnic or religious differences. The competition for a bigger share of the oil proceeds is behind much of the fighting.

One of the first things I learned about acting was, the only person you compete against is yourself.

I think most people that are looked upon as doing something daring don't necessarily think of it that way-they do what they have to do.

I've always wanted to work with Paul Newman. I had a couple opportunities in the past, and I didn't take advantage of it, so it was really fun to be working with him.
