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.

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.

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.

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 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.

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