For film and games, there is now a fantastic method of actors portraying characters which don't necessarily look like themselves. And yet you've still got the heart and soul of the performance.

A lot of actors on film sets... very often they're not paying attention to the physical world around them. I think through studying art, I've always had that awareness and that's something that I've wanted to bring in to go beyond acting... As a form of expression, they are intrinsically linked.

I was thinking about that. I was thinking, this is like our Boyhood; this is like our getting together over 12 years to make - this our Apehood! I mean, this is it! For me, the relationships, all of those things, over such a long period of time now with actors, but also seeing the characters grow, develop, and change, and go through different situations.

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.

[Greek] Theater started off and used masks and Kabuki, in the East, they used mask-work. And then, Commedia dell'arte in Italy and then, you know, we're part of an acting tradition and, and performance capture is no different.

What's wonderful about Tolkien and Shakespeare is that they show up your own individual microscope. They're so infinitely vast. You can reinterpret them in so many ways. Each age will have its own resonance with Lord of the Rings.

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.
