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.

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.

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.

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.
