Directing is one of my favourite things to do because I love telling stories and I love working with the individual artists and it's something that I really missed.

I love movies that make me cry, because they're tapping into a real emotion in me, and I always think afterwards "How did they do that?"

Sure, they were simple desk lamps with only a minimal amount of movement, but you could immediately tell that Luxo Jr. was a baby, and that the big one was his mother. In that short little film, computer animation went from a novelty to a serious tool for filmmaking.

Every single Pixar film, at one time or another, has been the worst movie ever put on film. But we know. We trust our process. We don't get scared and say, 'Oh, no, this film isn't working.'

Soon I learned that the worse the puns and jokes, the funnier they could be, if you knew how to deliver them.

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

To take full advantage of computer animation, you have to pay as much attention to the believable as you do the unbelievable.
