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.

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.

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

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.

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've been working in computer animation for 25 years. I'm obviously a devotee of the technology. I just think it's the one aspect of the medium that's going to continue to revolutionize the filmmaking. It's constantly changing and it's constantly opening up new possibilities. The technology is evolving where 2-D animation was ultimately limited by how long you could pay how many people to make a movie. I mean computers, not that it's in anyway a labor saving device, but it promises to open up exciting new technical possibilites.
