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.

My take is that acting is acting. A performance is a performance. With performance capture, if you don't get the performance on the day, you can't enhance the performance.

it's a weird thing with acting and it happens to a lot of actors, not just myself - it's like you're giving off an I really need to be loved today vibe. My worst moment recently is I fell asleep on the tube in London on the Victoria line 8:30 in the morning and I woke up and there were about five people with iPhones taking pictures.

Working with people you adore and love. There's just a sense, all the way through all of the movies [Planet of Apes], that you're very rarely in a position where you have great material that you're passionate about and a big audience who love it, and the detail and nuance, and the exquisiteness of the fantastic actors and director with great writing.

I'm definitely moving more towards directing now.

Performance capture is a technology, not a genre; it's just another way of recording an actor's performance.

The learning curve is 'The Hobbit' is being shot in 3D.
