I don't want to get pigeonholed just doing just family films and fantasy films... I don't really want to get pigeonholed just doing anything in particular.

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 kind of enjoy the limits. If you've got no limits, you can do absolutely anything, it's very difficult, actually. I always enjoyed working with machines like color photocopiers and letter-pressing type settings, things where the limits are very apparent. You push the machine to do something, and it tries to do its best, and it usually has wonderful qualities all of its own. Then you get a sort of dialogue going, and the limitations become qualities.

So I really love this very difficult feeling of being completely out at sea. I don't know what I'm doing, and I kind of like this feeling. So I think for the moment, I'm going to continue to try and nail film down in some sort of shape where I'm happy with it.

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.

Film gives me live actors, editing, music, sound, a huge and powerful toolbox to play with. If there is a problem for me, it is that film gives me too much. There is less room for the audience to add their side of the conversation.

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.
