'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.

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!''

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.

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.

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.

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.

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.
