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.

One of the first speaking roles I had was in a film called 'Svengali', with Peter O'Toole and Elizabeth Ashley. I was a waiter, and I had about three lines. And I was ready! I had been around people like that, and I knew they were just actors. All the work I had done, it was all there, and I felt like I knew all the mechanics.

I was raised on Westerns. They were part of what going into the movies was.

One of the interesting things about 'Saw' is that you don't find out about things in sequential or linear order. One of the things that fans have liked a lot is, we don't forget about details. They come back and reveal themselves as the story evolves.

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.

No matter what kind of significance leads you do, you learn a lot from doing schlock. The setup's the same, only you have to work twice as hard to make it the best as you can make it. And a lot of acting is not about acting but technology. Are you standing in your light? Are you out of your light? And if the sound guy's near you, please don't put the coffee cup down at that moment, because you're covering your lines. All of that stuff's going on in your head, so you learn a lot by doing whatever. In my view, never worry that something's not prime - A, number - one stuff.

Anything that exists on the human palette is, from my point of view, fair game for artists to portray. You don't have to go see it if you don't want to, so don't go.
