Everybody's a bird, locked up in a pretty cage. Sometimes you fly to a slightly bigger one, but you never quite have the courage to abandon captivity completely.

Reading a good comic is a creative act. Watching a film is often a more passive experience, and since I'm interested in engaging that conversational aspect of creativity, I'm trying to find ways of achieving that in my films.

Sometimes the things I learn making paintings or drawings - composition, colour, expressionism, texture - can directly influence the making of a film. Sometimes it's great that they are different, and simply taking a break from one medium to spend time with another, recharges the batteries and I feel refreshed.

I'm a huge science fan; I read a lot of science books. But I'm not a scientist, my interest in science is I love the facts, but I like to interpret those facts. They become the raw materials for stories and paintings and things.

But actually making pictures to look like my pictures, I've done it for so long, I'm kind of used to it now. So at the beginning of the process, designing and storyboarding everything, I sort of did all that. And then designed the characters, and doing the textures for the characters, and the texture maps to cover all the animated characters and the sets, I did those, because that's where my sort of coloring and textures get imprinted on the film.

There is nobody who is good or bad, it's just not like that. They all are complex individuals. They all see the world in their own way that makes complete sense to them. Nobody goes around feeling that they're evil - they think that they're doing the right thing. And so that seems to have something really important, big, and deep to say about human beings.

The human face is the most deeply ingrained image in our brains. It is the two dots and a dash we connect with as babies. It is the focus of our attention in our relationships with each other. The face and the human figure express all we are. Everything else - architecture, art, even landscape - we usually understand in relation to us.
