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.

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.

We can't worry about competition. Besides, you aren't competing with anyone but yourself. They have nothing to do with whether you make a good movie or not.

I've been working in computer animation for 25 years. I'm obviously a devotee of the technology. I just think it's the one aspect of the medium that's going to continue to revolutionize the filmmaking. It's constantly changing and it's constantly opening up new possibilities. The technology is evolving where 2-D animation was ultimately limited by how long you could pay how many people to make a movie. I mean computers, not that it's in anyway a labor saving device, but it promises to open up exciting new technical possibilites.

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.

If anything, it's a little intimidating because there's usually a lot of brilliant work and a lot of brilliant ideas out there that you wish you had thought of, or that you just admire for the originality of it or the difference from what you've been thinking of.

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.
