Transformers: Dark of the Moon is third and final episode in the saga."Produced by Steven Spielberg and directed by Michael Bay,Transformers: Dark of the Moon picks-up where the first two Transformers movies left-off, bringing the narrative to its natural denouement and giving-up some of the first two installments' scale and intensity in order to "go deeper into the mythos, give it more character development, and make it darker and more emotional." Official promotional materials for Transformers: Dark of the Moon summarize simply, "The Autobots learn of a Cybertronian spacecraft hidden on the Moon, and race against the Decepticons to reach it and learn its secrets, which could turn the tide in the Transformers' final battle." Adolescent boys of all ages may lament Megan Fox's decision not to reprise her performances as Mikaela, but they will appreciate the wisdom of Bay's decision not to replace her or contrive a substitute. A little shell-shocked from the epic failure of his Wall Street sequel, Shia LeBeouf attempts a sequel do-over in Transformers: Dark of the Moon ; and Josh Duhamel, Tyrese Gibson, John Turturro, and Ramon Rodriguez return for the final episode of the Transformers' saga. Perhaps most importantly, Peter Cullen once again puts his talents to work as the voice of Optimus Prime.
