I do very, very, very simple, skimpy doodles, nothing too committed. Because people tend to fall in love if they like it - if you color it in and they like it, then they want exactly those colors, even if they were just indications. You really have to do it as simple as possible so they can concentrate on the idea and composition. And then all of the energy goes into making the final piece. And the final piece can be anything - it can be a drawing, a painting, a collage - and usually, it's obvious what that should be. Usually, the idea dictates what medium you use.

The reason I love comics is that they DON'T move, and there is NO sound. As a creator I have to evoke those elements in the drawings and writing, and the reader has to create those elements in their own minds.

The inspiration is all in the script, in the text. So whatever it is, either it is a film or a book to be illustrated, anything. Everything you need to know is in the text. So the thing is trying to find right tone and voice, the right style, the right way of expressing the emotions in a story or in the location of the story, but it is all in the text.

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.

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.

I think the two jobs I dreamed of doing as a teenager were comic book artist and record cover illustrator. Maybe film director was in the mix as well, but that seemed to be an impossible mountain to climb.

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.
