“It’s a very difficult medium. Animation necessarily requires a pretty good draftsman, because you’ve got to turn things, to be able to draw well enough to turn things from every angle. You have to understand movement, which in itself is quite a study. You have to be an actor. You have to put on a performance, to be a showman, to be able to evaluate how good the entertainment is. You have to know what’s the best way of doing it, and have an appreciation of where it belongs in the picture. you have to be a pretty good story man.
