I never lost my appetite for acting.

I was an original member of the Actors' Studio.

I'd come out of the army after five years as a medic. I was a medical administrator and we ran hospitals, and I was a Captain in the army at the end, in 1945.

My wife says that stage acting is like being on a tightrope with no net, and being in the movies, there is a net - because you stop and go over it again. It's very technical and mechanical. On stage you're on your own.

One thing changes every evening: It's the audience, and I'm working my magic. I'm always learning from it.

Well, I was getting a lot of money then, and I wasn't getting any Hollywood films, so I just did those. I'd always do a play in between. Whenever I ran low on funds, I'd always rush off to do a movie somewhere.

Well, I go to the theater today, and its curtain - there is no curtain in this play; the lights go down and go up - and we start. And I live this character for two hours. There are only two of us in the play. And It's a complete experience.

John Huston was a superb master. He knew how to make good films. I did three things with him. One is called Independence. It plays in Philadelphia, for free. It's been playing there for 25 years.

Everyone thinks acting is easy. It’s far from easy, but it’s the most gratifying thing I do.

What is it in my makeup that makes me grab any offer and fly around the world? Will I ever be satisfied? Can’t I ever just rest?
