Acting, is not a profession for adults.

I have to act to live.

[May 1958, on playing Macbeth at age 30 and age 48] When you're a young man, Macbeth is a character part. When you're older, it's a straight part.

Of all the things I've done in life, directing a motion picture is the most beautiful. It's the most exciting and the nearest than an interpretive craftsman, such as an actor can possibly get to being a creator.

I don't know what is better than the work that is given to the actor-to teach the human heart the knowledge of itself.

If you're an artist, you've got to prove it.

Scratch an actor and you'll find an actor.
