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!''

I've worked with multiple directors throughout the 'Saw' series with a lot of conversations as they bring their particular installment to the screen. If I've been able to do anything throughout the course of these films, it's been to help shape dialogue and to try to make things as delicate and as intelligent as I can.

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.

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.

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.

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 is like a big jigsaw puzzle. When you put a jigsaw puzzle together, you put the bottom left corner together first, and then you find yourself working on the upper right corner... Thats the way Saw plays out.
