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.

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.

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.

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.

An actor puts himself in the hands of a director. And the director's first responsibility, obviously, is to tell the story, but the smallest thing that's not true reads on the screen. So if a director sees that an actor is not believable, he needs to help him become believable.

You know, the best-laid plans of mice and men... I like playing bad guys, and I don't have a problem doing that. They're interesting characters, and there's as many different kinds of bad guys as there are good guys - they're rich, they're strong, they're powerful, and so that's fine with me.

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.
