I've always used masks. I think it's a lot about the fact that masks often reveal a sort of subconscious element to a character. The mask is carved and given an expression or markings to reveal something, even though it's shielding the face. Even though it's hiding the face, it seems to reveal something underneath.

PhotoShop is a program I use all the time with my 2D stuff. And that's an extraordinary program - you really can do anything there, and I've never hit my head on the ceiling. The 3D stuff is incredibly complicated, monstrously complicated, but for the things that I want to do, I've found very simple and interesting ways, I hope, of making images without getting tied up too much in the maps and technicalities.

I like being able to do anything. I think that's healthy, doing anything and everything, rather than just getting completely obsessed with one particular genre or particular kind of work.

The filmmakers I really love are the ones that let me look through their eyes for a while. They have an aesthetic and social point of view.

Usually, the most difficult thing to do is photo-real stuff. Something that has to actually look like the real world, because it's just so difficult to do that. We're just so used to looking at the real world, our brains instantly see when something is not quite right.

When you just get fantasy stories that are about fairies or goblins, I just don't care. I'm never going to meet a goblin, it doesn't mean anything to me. So my definition of fantasy is very broad, it's anything to do with memory, or dreams, or ways of interpreting or making sense of the world.

I love the silent era because you can see the rules being written, the grammar of film being created. Most of my films are in some way love letters to the silent era.
