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.
Having done a lot of theater, I'm used to sustaining characters over long periods of time.
I do love nature, but I don't suppose I'd spent more time in zoos as a child than anyone else!
I think I spend most of my time not living in reality, actually.
I've been writing and wanting to direct for a long time.
People find it hard to get their heads around nominating a computer-generated character, but every time you see Gollum on the screen, that's me who is acting up there - even if it is behind a mass of pixels - and it's my voice you hear.
I think the actors in 'Greystoke' were amazing. They had a really good performance coach called Peter Elliott who's, of his time, one of the greatest simian performance coaches for actors.
I spent a lot of time on my own working out the physical vocabulary for how Gollum moved. As I say, I drew on a lot of Tolkein's descriptions of how he moves, but also the conceptual artist sketches.
