I worked with some of the best actors I've ever worked with: Mel Blanc and Don Messick. They could play a scene against themselves. Think of the characters that Mel created, and they're as good or better than any performance anyone has ever given. I mean: Daffy Duck! Think of the specific voice Mel gave Daffy Duck or Bugs Bunny or Porky Pig... It's just astonishing.
