Saw has been a unique experience in that Ive had the opportunity to work with some really great artists, and everyone has contributed in so many different ways, in all of the different departments of a film crew.

I'm a character and relationship guy, and even with the 'Saw' films, it's special-effects people's jobs to create these scary things. It's not my job. My job is to bring some sense of humanity to the character, no matter how evil he may be. The script is going to take me there.

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.

'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.

Watching a child first learn to crawl on a carpet somehow has more significance to you as you get a little older. Perhaps it is that you have suffered more.

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

The only thing worse than working acting in an airplane is working in a prison - they're cold, and the clanging and the noise, it just gets under your skin after a week.
