Horror fans are very passionate people, and they are very much into the 'Saw' thing. So they watch sometimes as carefully as the writers and producers do, in terms of the way the story plays out.

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.

Im an actor. The fact that Im involved in Jigsaw, I dont approach Jigsaw any differently than I approached The Nordic in The Firm or FBI Agent Stokes in Mississippi Burning. Its the same deal. Its just that the effect is sometimes different. So I say, people ask me, How does it feel to be a horror icon? Im thrilled. Its great.

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!''

There are a lot of considerations that come into play when you craft one of these 'Saw' scripts, and there's only so much you can put into them.

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 learned that I could not do enough work; it's always incomplete. When you ask a question, the answer will raise four more questions, and those four will become eight.
