Bob Clampett used to do quick sketches for his animators when he handed out scenes to them. They didn't have all the detail in them, but described the extremities of the actions and expressions. This is partly what makes his cartoons look so different from everyone else's. You see those same animators working on other directors' cartoons and their drawings and animation are nothing like their Clampett animation.
Milt Gray asked him what to call these sketches-were they "layouts"? or anything typical? Bob didn't have a name for them, so Milt came up with "energy sketches" which I thought was perfect.
Correct me if I'm wrong Milt.
