John DiMaggio as Leadfoot in DOTM, Who was the Voice Director for the movies? I had this little Theory since DOTM Came out. How did John DiMaggio AKA Bender joined the Transformers Voice Cast for the Movies? Is it because he voiced Sideways in the ROTF Game? The Joker in Under the Red Hood? Or maybe he did not got a role in the 2nd flim? I even hoped that he would appeared in the 3rd film, and guess what? He did. Anybody else got a say in this? Do you think Charlie Adler or Michael Bay was the voice director for the movies?
