Voice actor info

Leonard Nimoy as Galvatron -Known to most people as Spock's actor from the Star Trek series, Leonard would make his return to Transformers in 2011. In Transformers: Dark of the Moon, he voices Sentinel Prime. For season 3 and 4 of The Transformers, Frank Welker would voice Galvatron.

Orson Welles as Unicron -"You know what I did this morning? I played the voice of a toy. Some terrible robot toys from Japan that changed from one thing to another. The Japanese have funded a full-length animated cartoon about the doings of these toys, which is all bad outer-space stuff. I play a planet. I menace somebody called Something-or-other. Then I'm destroyed. My plan to destroy Whoever-it-is is thwarted and I tear myself apart on the screen." -This was what Orson had to say about his role in his biography. Orson died before the movie was released, but he did have all of his lines recorded.

Judd Nelson as Hot Rod/Rodimus Prime -One of Judd's most famous roles is John Bender in The Breakfast Club, whilst his other roles include Jack Richmond in Suddenly Susan and Rodimus Prime in his single episode appearance in Transformers: Animated.
