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

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.

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.

Toys are put on this Earth to be played with by a child.

Walt Disney had always tried to get more dimension in his animation and when I saw these tapes, I thought, This is it! This is what Walt was waiting for! But when I looked around, nobody at the studio at the time was even halfway interested in it.

People who get into animation tend to be kids. We don't have to grow up. But also, animators are great observers, and there's this childlike wonder and interest in the world, the observation of little things that happen in life.

What's fun about the story development at Pixar is it's a journey. You don't just write a script and then that's the movie you make. It's just constant evolution and being open to that and that collaboration with the voice actors and with the artists and animators at Pixar.
