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.

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.

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.

After 'Kong,' my knuckles have never recovered because I had to wear very heavy weights on my forearms and around my hips and ankles to get the sense of size and scale of the movement of the character You are telling your body that you are these things and that you're feeling these thoughts and that you're experiencing these experiences.

Gollum is Gollum - though in 'Lord of the Rings' he's 600 years old and in 'The Hobbit' he's 540, so he looks a little bit more handsome.
