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.

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.

On these feature films there are people on the staff who can draw 100 times better then I can, and animate better then I can, and light better then I can, write comedy better then I can. I basically am in the middle of kind of a creative typhoon and I'm just kind of talking the film up on to the screen. Minute to minute, meeting by meeting, day by day.

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.

I remember feeling that technology was like trying to draw with your foot. In a ski boot. It was the most indirect way to work imaginable, but the potential had us all excited. I started in stop motion.

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.

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.
