I'm the biggest fan of animation. I love the history of animation, I know it well.

I quickly realized that this medium had a lot to offer someone like me. To do Disney-quality hand-drawn cartoons, you have to be a master of two art forms. Seriously, you have to be able to draw like a Leonardo da Vinci or a Michelangelo. But also you have to know movement and timing and control that through 24 frames a second.

In computer animation, every detail has to be thought out, designed, modeled, shaded, placed and lit. The more you add, the more computer memory you need.

The hardest thing to get is true emotion. I always believe you need to earn that with the audience. You can't just tell them ok, be sad now. Humor, you can add. Even to the last minute you can be adding little bits of humor. But the true earned emotion is something that you really have to craft.

Humor is the easiest to achieve; the 'heart' is always the toughest, because you can't tell people to feel a certain way.

The art challenges the technology, and the technology inspires the art.

Animation is the one type of movie that really does play for the entire audience. Our challenge is to make stories that connect for kids and adults.
