A Transformer Voice Has Been Cast

IMDB.com has updated the Transformers movie entry to show that Mark Ryan has been cast...as a voice. Voice for what you ask? No one is telling, not even him on his website, "I can't say too much as we're all sworn to secrecy and the project's script and imagery concepts are being very closely guarded by the producers. I'm on set, interacting with the actors in a most unusual way and having a great time doing it!"

Not a clue who this person is, picture doesn't ring a bell so just for giggles and based on various set reports on what is being filmed, it seems about the only Transformer that has been so far is Bumblebee, so that's my guess on who he is the voice for. Not entirely a shot in the dark but not based on any concrete information at this time either.
