I think that the best movies are made, not from a point of view that depends on your personal history, whether it's the color of your skin or the politics that you had or the place that you come from, but from a point of view of an understanding of human nature, an understanding of history, and an understanding of what motivates people.

American Graffiti was the first movie where the director let me have any input. It was the first time anyone ever listened to me. George thought my character should have a crew cut, but I wasn't happy with that idea. I'd always had pretty long hair back then - in college, particularly - so I told George my character should wear a cowboy hat. George thought about it and he remembered a bunch of guys from Modesto, California, who cruised around, like my character, and wore cowboy hats, so it turned out that it actually fit the movie.

[In relationships with a directors] I want to be able to give and take, and I can't name what it is: respect, energy, investment in the task, focus, humor, intelligence, but I always feel responsible for taking the money.

For some directors, I'm the actor from hell.

If I were a serious person, I'd probably have a real job.

The third time you say a thing it sounds like a lie.

I don't take trouble at all to conform a screenplay to my iconography. I don't say, "We can't do that - the audience wouldn't accept it." I try to take the limitations of what is required to play a leading character and then screw with them.
