The best way, of course, to understand the animator is to see that he parallels the actor. He has the same responsibility a fine actor has. [...] Even the people who write about animation just don't seem to understand that when you have a drawing, you don't have a character. [...] "This is the first Bugs Bunny" has no meaning. It's how Bugs came to stand and move and act, and what his feelings were, and his thoughts, and what kind of personality he was. That developed over a period of time. And you need fine animators to do that.
