For me, part of the fascination with making animation is you go to a place; it's a complete immersion in someone else's fantasy.

You win the Oscar, you get to go into just about anybody's office for a month. I had a lot of meetings.

I get a lot of credit for Tron. They called us scene choreographers back then because the animation unit wouldn't let us be called animators because we were working on computers. And we were some of the first people ever to make 3-D computer animation.

Fox came to us with the concept for ICE AGE and they came to us with the first draft of the script. They also gave us a mandate to make it into a comedy from what was previously a rather dramatic action concept.

For me, part of the fascination with making animation is you go to a place; it's a complete immersion in someone else's fantasy.

I think I probably am doing animation because I started as a kid and I learned on my own, and I worked by myself a lot. It's the only thing I really prepared myself to do in any kind of depth. And I've just kind of imbibed the technology and techniques and the thinking about telling stories this way. It just feels natural to me.

Someday, I'd like to sit down with a small group of people, in a relaxed environment, and make a film that feels more independent. That way we can be a little more free in terms of storytelling and subject.
