It must be “add some illustrious vocal credits to your summer blockbuster" week. Just a day after Warner Bros. announced that Oscar-winner Geoffrey Rush would be providing the voice of Tomar-Re in Martin Campbell’s Green Lantern movie, Paramount let it be known that the iconic Leonard Nimoy would handle the vocal chores for the robot Sentinel Prime in Transformers: Dark of the Moon.

Sentinel Prime is the “ancestor” of Transformers “good guy” autobot Optimus Prime. In Dark of the Moon the wreckage of Sentinel Prime is found on the moon by the Apollo 11 Astronauts and brought to Earth where he adopts the vehicle disguise of a Rosenbauer fire truck. 

Nimoy, who is most famous for his role as Mr. Spock in Star Trek, is no stranger to the Transformers universe. In 1986 he provided the voice of Galvatron in Transformers: The Movie.
