"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."
