I enjoy high-speed about-turns in thought.

Originally, I thought, 'Gollum's such a fantastic character, why are you doing him CG? Surely you need to be able to humanise him as much as possible - he's so full of pathos and real emotion.'

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 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.

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.

More and more good actors are now transmigrating into the videogame space and playing roles there because it's where my generation of kids get stories from.
