Optimus Prime Takes Shape For 'Transformers 2’ As Voice Artist Peter Cullen Returns To Work

Optimus Prime from 'Transformers'Production news for “Transformers: Revenge of the Fallen” has been coming fast and furious lately, from behind-the-scenes video diaries to details about which new robots we’ll see in the sequel. But at the heart of it all is Optimus Prime -- the strong and valiant leader of the Autobots -- and just as the human cast is busy doing their part, the man behind the “Roll Out” is also getting back in the trenches.

“I’ve only done the opening,” voiceover legend Peter Cullen told MTV News, updating us on the lengthy process of recording lines for the film. “[Michael] Bay brought me in to get them started on some of the animation part of it. I think they require a voiceover for it, [and then] we’ll get into the main stuff more towards the end of the fall…November, perhaps.”

And while Cullen will remain off-camera, like in the first film, some of him will find a home on the synchronized face of his alter-ego, Prime. “They focus a camera on my mouth,” he exclaimed. “It’s like ‘Oh my God, they’re looking into my mouth!’ It’s like going to the dentist.”

“Transformers: Revenge of the Fallen” hits theaters June 26, 2009. A new Blu-ray edition of the first film is available in stores now.
