A star on a movie set is like a time bomb. That bomb has got to be defused so people can approach it without fear.

Human beings are always going to find interesting ways of making a mess of their lives. It's human nature.

I don't believe that relationships are fixed things. People are necessarily complex and confused beings. We don't always do the right thing, say the right, and behave the same way or the way we always want to behave.

The way I reacted to 9/11 was I decided I didn't want to do any movies that are sad or critical. I decided I didn't want to make my living depressing people or making them go home sick, so I just decided I wanted to do comedy for a while and study it for a while. It doesn't mean everybody should do that, but that was my reaction.

I don't play golf competitively. I tell everybody that I cheat so they won't gamble with me. That's why you can't watch football. Everybody's gambling. They don't want to watch the game; they watch the spread.

Early on, if I was alone two three nights in a row, I'd start writing poems about suicide.

I was particularly proud of my performance as the Joker. I considered it a piece of pop art.
