My dad was working abroad, in Iraq, and he was a doctor. We used to go and visit him, in Baghdad, off and on. For the first ten years of my life, we used to go backwards and forwards to Baghdad, so that was quite amazing. I spent a lot of time traveling around the Middle East.

Basically we're puppeteers and if you're there and you're in the character, the puppet is going to look good. It's going to breath life and I think once they find out how to trust this system, you just forget about it and just perform, then it's just second nature, it just becomes easy.

Animators do amazing working translating and interpolating the characters [in the Planet of the apes], the facial performances. What we're creating on set - if you don't get it on the day, in the moment, on set, in front of the camera, with the director and the actors. The emotional content of the scene and the acting choices.

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.

Motion capture is exactly what it says: it's physical moves, whereas performance capture is the entire performance - including your facial performance. If you're doing, say, martial arts for a video game, that is motion capture. This is basically another way of recording an actor's performance: audio, facial and physical.

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.

'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.
