We've previously reported on Transformers: The Movie game content at GameTrailers.com, and there's more stuff up now.  The trailer for the game, narrated by Peter Cullen's Optimus Prime, is available in stunning, ear-splitting HD!  There's also a behind-the-scenes piece with Peter Cullen discussing his return to the role he originated, complete with a bit of vocal coaching.

Check both pieces out at the GameTrailers page.
