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.

'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.

Saw fans are manic, when it comes to details, so they're going to say, "Wait a minute! Why is that like that? It wasn't like that before." And, they're right.

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

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.

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.

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.
