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.

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.

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.

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

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.
