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.

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 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'm very happy to be a part of a very successful piece of art, as the 'Saw' films have been. One gets into this to participate. It's the coming together of a good story. So, that aspect of it has been just splendid. It really has nothing to do with me or my popularity. I'm fascinated.

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.

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.

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.
