Noah, from 'The Young Lions' (1958), was the best performance of my life. I couldn't have given more of myself. I'll never be able to do it again. Never.

Nobody ever lies about being lonely.

I keep my family out of my public life because it can be an awful nuisance to them. What's my mother going to tell strangers anyway? That I was a cute baby and that she's terribly proud of me? Nuts. Who cares?

James Dean's death had a profound effect on me. The instant I heard about it, I vomited. I don't know why.

Look, I'm not odd. I'm just trying to be an actor; not a movie star, an actor.

Look! Look! If you look really hard at things you'll forget you're going to die.

A man should be what he can do.
