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.

What made 'Ice Age' work is that it had its shiny candy coatings, but inside was a soft, creamy center.

The most fun is to inhabit the world where cartoon physics is king. And that just means that things move with kind of an energy and exaggeration and appeal that is different from what we see in our world. We're bound by, at least, Newton's Laws of physics here and in animation we're not. So, director's can be extremely eccentric, you can sculpt motion in animation in a way that you just can't do any other way. In any other performance medium.

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'm surrounded by a lot of live-action movie professionals, and I'm just taking their lead, as far as what to schedule to do next. I'm guessing the challenge is going to be not having two characters together, and shooting the live-action without having the animation. In animation, you get to get in between every frame and you work it all out together.

I grew up watching classic animation, and I have always felt that the roots of animation is in fantasy and taking it in places that you can't go, any other way.

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.
