If you're an impressionistic painter and you want to paint expressionism, you've got to change. You've got to figure out a way to do it and do it. If you've been playing jazz all your life and you want to start to play rock n' roll, blues, then do it.

What's interesting is that you can have a set that's very calm, very smooth, very cooperative... and end up with a terrible movie. And you can have a set that's really horrible as far as relationships and volatility, and come up with a great movie. Sometimes that energy gets infused into what ends up on film - it's interesting in that way.

In the the late seventies and early eighties, I played background roles in thirty movies... Woody Allen movies, Scorsese films, you name it. Whatever was being shot in New York, I was doing stand-in and background work because I wanted to be close to the camera; I wanted to see what was going on.

I'm always amazed... I took my 11-year-old to an oceanography camp, and these girls came over to me, and my son was like 'Oh here we go, Dad,' because they had been looking. They were like, 'You're the guy, aren't you?' And I said, 'Well, maybe.' They said, 'He is, he's the guy on 'Charmed!''

'Saw VI' has a really interesting theme about the ripple effect. Everything you do affects the guy next to you, which affects the guy next to him, which affects her over here. And you might think that what you're doing is not that significant, but just the way you respond to other people makes the world the way it is.

Actors have seven tracks going in their minds: They've got all the research they've done for the part, then they have whatever the director asked them to do, then they've got what the departments like special effects need them to do.

One never wants to do anything that's going to break that 'sculpture of the character' that's been done so far, or make anything that's been done so far become illogical in any way, so you always want to try to connect when you're doing a series of films that has a continuous character.
