The actor signed on as the voice of Autobot leader Sentinel Prime in ''Transformers: Dark of the Moon''


Leonard Nimoy (right) knows this sounds a little illogical. After announcing his retirement last April in the wake of his Spock role in J.J. Abrams’ 2009 Star Trek reboot and his guest turn on TV’s Fringe, the 80-year-old actor has now signed on as the voice of long-lost Autobot leader Sentinel Prime in Transformers: Dark of the Moon. ”I’m doing it! I’m doing it! I’m back — back after, what is it, 25 years or something?” says Nimoy, referring to his work as the voice of Galvatron in 1986’s animated The Transformers: The Movie.

”I have been through many resurrections in my career,” he says. ”I have died and come back. I have left and come back. I’ve been canceled and come back. I did intend to not do any more work. And the fact is, I don’t consider this work. This is great fun.” Nimoy is also rumored to be the voice of the dragon Smaug in Peter Jackson’s The Hobbit, though he says only: ”I have heard about that rumor, and that’s all I know about it.”

Nimoy has already recorded two sessions with Transformers director Michael Bay. ”I don’t think I’m very privy to any plot points, but I’m seeing some interesting footage.” Asked to describe Sentinel Prime, Nimoy says, ”Complex,” and then ”Why are you laughing?” Then he laughs too.
