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.

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.

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.

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.

Honestly, I don't go out of my way to see animated movies. I'm mostly influenced by.. the films I tend to like are the small films, small personal stories. With characters you can believe.

This technology will obviously become more prevalent. Who knows what will result? One thing is certain, computer technology will revolutionize the way we tell stories as much as movie film has.
