A gem of a short film has a sense of pure joy in animation that is different from anything you see in a feature film.

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

If you're sitting in your minivan, playing your computer animated films for your children in the back seat, is it the animation that's entertaining you as you drive and listen? No, it's the storytelling. That's why we put so much importance on story. No amount of great animation will save a bad story.

Animation is the only thing I ever wanted to do in my whole life. I have no desire for live-action or anything else.

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.

Every technology that comes into filmmaking is first a gimmick. Think about sound with 'The Jazz Singer' or the first colour or surround sound - it takes a while for filmmakers to understand how to use it.

You cannot base a whole movie on just the imagery alone. It has to be the story and the characters.
