Your primary tools, as an actor, are observation and imagination. You can pretty much get everything you need from that, and you do. It brings back that element of pretend.

I've played the clarinet since I was a kid. I love to sing, but I'm not much of a singer. Let's say that when it comes to vocalizing, I have the soul of Billy Bigelow but the voice of Jigger Cragan.

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.

What has emerged as I've gotten older is simplifying the characters I play, unless the role calls for something that is arcane or ornate.

My criteria for doing theater has always been slightly different than my criteria with movies, in that there are a lot of reasons to do films, having to do with location, money, and first and foremost having to do with script and role and director.

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.

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.
