Optimus Prime and the rest of the Autobots return in Transformers: Dark of the Moon, the third instalment of the blockbuster movie franchise. A dark secret is revealed as the Autobots discover a hidden Cybertronian spacecraft on the moon that may threaten Earth’s existence. It’s a race against the Decepticons, who themselves plan to unleash its destructive power on the world.

Joining Autobot leader Optimus Prime are stalwarts Ironhide, Ratchet, and Bumblebee. They will be joined by new Autobots Sideswipe, Mirage, and Silverbolt. The mysterious warrior Sentinel Prime, Optimus’ predecessor, also makes an appearance, though his true intentions are unknown.

Shia LaBeouf returns as Sam Witwicky, friend of the Autobots and Earth’s closest link with the sentient alien robots. Model Rosie Huntington-Whiteley, as Carly Miller, replaces Megan Fox as Sam’s love interest. Familiar faces Josh Duhamel, Tyrese Gibson, and John Turturro also return in their respective roles. Music band Linkin Park’s single Iridescent will be the theme song of the new movie. The popular rock band also provided the theme songs for the first two movies with the singles What I’ve Done, and New Divide. American rock band Paramore will also contribute to the movie’s soundtrack.

The Dreamworks robot franchise was adapted from the Hasbro toy line of the same name released in the 1980s. The franchise’s box office success – over $1.5 billion in grosses worldwide – has revitalized the toy line’s popularity. New toys based on the updated robot models have been selling well, and likewise for the video game adaptations released concurrently with the movies.

Director Michael Bay has said that Dark of the Moon will be his last with franchise, but the series is still expected to continue with or without his involvement. Bay is best known for his big budget action flicks, and stylistic action choreography, as seen in movies like Bad Boys, Armageddon, and The Rock.
