Leonard Nimoy joins 'Transformers: Dark of the Moon' voice cast
Here is some news that should make Transformers: Dark of the Moon live long and prosper in the hearts of sci-fi fans.
Mr. Spock himself, Leonard Nimoy, has joined the film as the voice of Sentinel Prime, the predecessor of Optimus Prime whose wrecked body is seen in the teaser trailer, found crash-landed on the moon by the Apollo 11 astronauts in 1969. Later, after being brought to earth, he takes the disguise form of a fire engine in the movie’s massive, climactic battle through Chicago.
Oooooh So from Galvatron to Sentinel Prime interesting but so awesome to have him back in it
