'May the Force be with you' is charming but it's not important. What's important is that you become the Force - for yourself and perhaps for other people.

Nothing shocks me. I'm a scientist.

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.

You may get real tired watching me, but I'm not going to quit.

When I first started out, I was a bad actor.

That's always my ambition is to create a character out of what will help tell the story. I've never been an actor to say my character wouldn't do that, because he should do that in order to help tell the story.

I am not the first man who wanted to make changes in his life at 60 and I won't be the last. It is just that others can do it with anonymity.
