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.

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.

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.

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.

What's interesting is that you can have a set that's very calm, very smooth, very cooperative... and end up with a terrible movie. And you can have a set that's really horrible as far as relationships and volatility, and come up with a great movie. Sometimes that energy gets infused into what ends up on film - it's interesting in that way.

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.
