I think it's important to never play 'crazy' - you have to know what kind of crazy you're playing.

Sometimes you have to exercise your insanity, to really make it strong.

Insanity runs in my family. It practically gallops.

I always wanted to play a mental patient. I was fascinated with playing crazy people in college, and I don't know if I ever quite perfected it.

Playing sick. That is so hard to do. It has to be a total mental challenge, as well as the physical challenge.

In individuals, insanity is rare; but in groups, parties, nations and epochs, it is the rule.

Insanity in individuals is something rare - but in groups, parties, nations and epochs, it is the rule.

You don't really ever think you're that crazy person you're playing.

It takes madness to find out madness.

It's insane but it's a great insane.
