If you're doing a biography, you try to stay as accurate as possible to reality. But you really don't know what was going on in the person's mind. You just know what was going on in the minds of people around him.

If a person doesn't change, there's something really wrong with him.

I'm not one of these guys who sits around saying, 'Gee, I mean, the person had a strange childhood and that's why he's doing this horrible thing. Poor Jeffrey Dahmer. He's just had a bad childhood and that's why he's eating people.' Wait a second! This person should be removed from the planet.

Just try not to ingest a lot of fats, and just try to eat carefully.

Comedy isn't necessarily all dialogue. Think of Buster Keaton: the poker face and all this chaos going on all around him. Sometimes it's a question of timing, of the proper rhythm.

If you're really satisfied with your position on something, you just say, 'Hey;' you just very calmly present something.
