I wouldn't say 'Avatar' changed my life, but it definitely changed my career.

I've always been curious as to why one man jumps out of a fox-hole with a grenade and charges a machine gun nest and his buddy, who sits right there next to him, sits there cowering. My feeling is that the different is tiny between the two.

In a rehearsal room, your real resource as an actor aren't the things around you; your resources are your imagination and your director and the other actors. In those close quarters, your imagination and your skills are what you turn to.

Theater, because of the commitment, it has to be a great role and a great play to me. It takes a lot out of you.

I was relatively buff (before 'Avatar'), because I was working in a tanktop half the time on stage, anyway, but I just went kind of into hyperdrive after that and really worked to beat that old body into shape, to get that carcass where...I didn't want to be looking at it and see anything hanging where it shouldn't be hanging.

I love the stage. It's terrifying in a way that film and television is not. When you're about to go out, and you're adrenaline just gets out of control, and that can be really daunting.

I love scenes that are just emotional give and take. By the same token action sequences are great to do. They have their own unique demands and requirements. So I take it as it comes and hopefully you can get a good balance of all of that stuff.
