Pixar films are not realistic. They are believable for the worlds we are creating.

We make the kind of movies we like to watch. I love to laugh. I love to be amazed by how beautiful it is. But I also love to be moved to tears. There's lots of heart in our films.

I worry about kids today not having time to build a tree house or ride a bike or go fishing. I worry that life is getting faster and faster.

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.

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.'

Computers don't create computer animation any more than a pencil creates pencil animation. What creates computer animation is the artist.

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