Nothing's occurring in animation - you manufacture everything.

For me, some of the happiest moments on a live-action film are the awkward moments. One actor says something to another actor. They didn't expect that performance from that actor; that affects their return performance.

All the traditional westerns are about choice and the individual. When progress comes it's much more difficult to define the individual in that world.

There's so much work in making movies, it's so easy to tear one down. When I watch a movie, even one that I don't particularly enjoy, I'm constantly impressed at the work that's in it. I respect the craftsmen and women. I tolerate a lot of movies that maybe other people don't, just because I know what goes into them.

Animated films are so precisely engineered - right down to forming lines of dialogue with words pulled from several different takes - how do you translate that spontaneity from the live-action to the digital realm?

My respect for animators and animation directors has gone way, way up and it is just not something you can phone in.

I'd love to do a PG-13 animated adventure. It would be great.
