One of the big technical advances that's really great looking is the water.

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.

You have to do three things really well to make a successful film. You have to tell a compelling story that has a story that is unpredictable, that keeps people on the edge of their seat where they can't wait to see what happens next. You then populate that story with really memorable and appealing characters. And then, you put that story and those characters in a believable world, not realistic but believable for the story that you're telling.

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.

I just devoured all of his [Buster Keaton’s] films because his sense of comic timing was amazing. He’s the closest a human being has ever come to a cartoon character. And I was just amazed at his sense of character and timing, the humor. It's all just so…sophisticated, even when you watch it today.

I believe in research you cannot do enough research; believability comes out of what's real.

You make a movie to entertain audiences. That's why you make a movie. The product sales is because people love the characters, and to me, that is a testament to how our movie has become so ingrained in family's homes all around the world and that's why I make movies.
