In terms of animation, animators are actors as well. They are fantastic actors. They have to draw from how they feel emotionally about the beat of a scene that they're working on. They work collaboratively.

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.

It's really up to the acting community to be willing to be educated about what performance capture is in order to fully appreciate it as acting. It's not a type of acting, but rather the use of technology to harness an actor's performance and translate it into an ape, another animal, or an avatar of some kind.

When I played Gollum in 'Lord of the Rings,' if I was climbing up the side of a mountain, which I physically did, you know, I was on every single occasion swimming through streams, all of that, that wasn't captured. That was filmed on 35 millimeter, and for certain of those shots, it was rotoscoped and painted over.

The whole chameleon thing about acting. That's why I'm moving towards directing - it's a much more healthy occupation.

In a personal way, to do with family and the father-son relationship, in a kind of artistic way with regard to him being an art student. I also studied the visual arts at Lancaster University. I then decided to become an actor as he was becoming a musician. And then as an actor/performer, we have similar sort of interests - music hall and that whole world. So, there's a lot that I felt connected with.

I'd already started directing short films when we were doing 'Lord of the Rings,' then videogame projects. So Peter's known that I've been heading towards directing for a long time. But I always thought my first outing would be a couple of people and a digital camera in the back streets of London somewhere!
