|Bob Clampett's model sheet for Daffy Duck|
A character design is more about acting performance than it is about static design. Warner Bros. director Chuck Jones put it this way:
"When you have a drawing, you don't have a character. It's like seeing a photograph of an actor, and then saying, 'We're choosing this actor.' I don't understand these casting directors: what do you know when you look at him? OK, he looks the part, but until I see him move, I haven't any idea whether he is the part or not. If it's anything, it's the bodily style, bodily movement, gestures, mistakes that you make, that identify you."
"The same is true in an animated 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."From Chuck Jones: Conversations by Maureen Furniss.
