Last night I watched an episode of Knight Rider courtesy of 4OD/Homechoice. I picked 'Trust Doesn't Rust' since it's one of the KARR episodes.
I was sure the voice of KARR was Megatron's, but a quick IMDB showed it was actually Peter Cullen, who played Optimus Prime. Apparently he also played Venger in the Dungeons and Dragons cartoon. In fact he's been in loads of things.
He's also doing Optimus Prime on the new film.
I thought this was fairly cool for a few minutes. So I thought I'd bore whoever was foolish enough to open this thread with it too.
