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.

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.

'The Hobbit' was one of the first biggish books I ever read. I remember vividly the 'riddles in the dark' passage, and it meant a lot to me to finally get to play it after all these years.

But that's not what an actor does. An actor finds things in the moment with a director and other actors that you don't have time to hand-draw or animate with a computer.

People think, 'Oh, well how can 'The Hobbit,' which is one book, become three films?' But you can take one line from an appendice and it turns into a whole sequence.

I've done a fair amount of that stuff... when we did 'Lord of the Rings' the transformation sequence from Smeagol to Gollum was a 19-hour make-up job. You have to have a kind of zen button that you press and allow the mind to be focused in a certain way.

There are no rhymes or reason, actually. Having said that, you know, cause there are people who are absolutely single-minded about their process and they can still come up with great work. But (what) I enjoy and it's the same, I suppose, as I became more of a family man, I enjoy, I enjoy an atmosphere where it, you know, doesn't have to be about conflict to get good results.
