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.

I was one of the few people who thought Star Wars was going to work, and I hadn't even seen any special effects.

The only thing hard about being an actor is being out of work. So, when you get a job - that part ain't hard at all.

You get a sense of reference there. You feel part of something that's got order and balance and harmony to it. All the distraction and noise, all the confusion of misplaced, misdirected energy just don't happen there.

I was desperately unhappy with it [Blade Runner]. I was compelled by contract to record five or six different versions of the narration, each of which was found wanting on a storytelling basis. The final version was something that I was completely unhappy with. The movie obviously has a very strong following, but it could have been more than a cult picture.

When I was a carpenter, I once worked with this Russian lady architect. I would tell her, ‘Look, I’m terribly sorry, but I want to change that a half inch,’ and she would say, ‘No limit for better.’ I think that is a worthy credo. You keep on going until you get it as close to being right as the time and patience of others will allow.

You have to have a darkness...for the dawn to come. You have to have experienced difficulties and challenges to fully appreciate and be grateful for success.
