Leonard Nimoy – Once retired actor Leonard Nimoy came out of retirement to help voice Prime in director Michael Bay’s prequel “Transformers: Dark of the Moon”.
Leonard Nimoy who retired from acting last year said he’s happy to be back. Leonard will voice Prime, the predecessor of Optimus Prime.
Michael Bay admitted he had reservations asking the actor who’s best known for playing Spock in Star Trek to take on the role.
Michael states to Entertainment Weekly, “I was too scared to ask him. Plus, he’s married to Susan Bay, who’s a cousin of mine. So I had to be careful. I’ve met him at family functions. But he told me, ‘I would be honoured. I’m glad to be back!'”
