I am a bit evangelical, I know, but performance-capture is still misunderstood.

Performance capture is a tool that young actors will need in the next 10, 20 years. It's on the increase, as you say. It's not going away.

When I first was offered the role on Rise [of the Planet of the Apes], I always played Caesar as a human being within ape skin.

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.

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!

'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.

The difference between the big budget films I've done is the length of time. But in terms of the day-to-day, you're still going on to set, you're getting into character, and you're going and doing your job, so there's absolutely no difference. It's just the structure around it and the length of time. But in terms of budget and money, it doesn't really manifest itself.
