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.

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.

All I can do is do my best work, try to create the best kind of moment to moment reality that I can do. That's what I do. I'm an actor. And all the rest of it is like baseball. You hit the ball. Sometimes it goes in the hole. Sometimes it goes to the player.

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'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.

There's the moment in 'Saw' where I get up off of the floor at the end. That was shocking, because no one expects it. I thought they did that really, really well.

I try to think of acting in terms of thinking and doing. People think of it as, "Oh, let's get inside this guy." They think that acting is being, or feeling, or emoting. It's as much doing. One of the first things you do as an acting student is ask, "Can you say words and do a task at the same time, like sweep a floor?" You get to watch the human condition, and there's always a "doing" aspect of it. This couple, they're carrying backpacks, where are they going? Students? Or are they carrying instruments? It stimulates the imagination. So acting is doing ... and I forget how we got off on that.
