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 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'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.

You look at Japan and Hayao Miyazaki's films are the biggest films ever made in Japan; domestically there and they play to critical acclaim around the world. He won't put more then 5 or 10 percent computer imagery in his movies. It's disappointing to me. It's a silly choice that some studios made to move out of animation. It's part of the unfortuneate preconception that I think the public has going into see 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.
