I'm working from home a lot. That's very unusual because I'm away a lot, sometimes working on the other side of the world for long periods of time. So, it's hard to manage in the sense that I want to be the best dad I can be but it's almost harder when you have your kids outside the door.

The matter is - we are actors playing roles [in Planet Apes] and they happen to be in this instance apes but there's no difference. In the scenes that we're playing, if we were to block out the scenes as actors in costumes, it would be no different.

My agent told me they were casting for the voice of Gollum. I hadnt read The Lord of the Rings, but I read the script and realized what an amazing role it was. I developed a voice for the audition tape, then met Peter Jackson and Fran Walsh at the auditions and fell in love with them both.

But I think there's something wonderful and extraordinary about climbing on your own and just that kind of relationship to the environment. I'm very addicted to the mountains. You know, so, I do like that solitude.

Performance capture is a genre of acting which is not going to go away, it's going to proliferate more and more. I'm passionate about it, and I love it. It's the most liberating tool an actor has, because you are not limited by your own physicality, look, or color of your eyes.

What you can do with visual effects is enhance the look of the character, but the actual integrity of the emotional performance and the way the character's facial expressions work, that is what is going to be created on the day with other actors and the director.

I've always thought of acting as a tool to change society. I watch a lot of actors and I see panic in their eyes because they don't know why they act and I know why I act. Whether I'm a good or a bad actor, I know why I do it.
