Transformers: Dark of the Moon (2011)

Transformers: Dark of the Moon is a 2011 American science fiction action film directed by Michael Bay and starring Shia LaBeouf, Josh Duhamel, John Turturro, Tyrese Gibson, Patrick Dempsey, Kevin Dunn and Rosie Huntington-Whiteley.

Plot: In 1961, the Ark, a Cybertronian spacecraft carrying an invention capable of ending the war between the philanthropic Autobots and the malevolent Decepticons, crash lands on the dark side of Earth's Moon. The crash is detected on Earth by NASA, and President John F. Kennedy authorizes a mission to put a man on the Moon as a cover for investigating the craft. In 1969, the crew of Apollo 11 lands on the Moon. In the present, the Autobots assist the United States military in preventing conflicts around the globe. During a mission to Chernobyl, to investigate suspected alien technology, Optimus Prime finds a fuel cell from the Ark, discovering that it had survived its journey from Cybertron. The Autobots are attacked by Shockwave, who manages to escape. After learning of the top-secret mission to the Moon, the Autobots travel there to explore the Ark. They discover a comatose Sentinel Prime – Optimus' predecessor as leader of the Autobots – and the Pillars he created as a means of establishing a Space Bridge between two points to teleport matter. After returning to Earth, Optimus uses the energy of his Matrix of Leadership to revive Sentinel Prime. Meanwhile, Sam Witwicky is frustrated that he is unable to work with the Autobots and is failing to find a job. He also becomes envious of the close relationship between his new girlfriend, Carly Spencer, and her boss Dylan Gould. After finding work, Sam is provided information by his eccentric co-worker Jerry Wang about the Ark, before Jerry is assassinated by the Decepticon Laserbeak. Sam contacts the now-independently wealthy Seymour Simmons, and together they realize that the Decepticons and their leader, Megatron, are murdering people connected to the American and Russian space missions to the Ark.

They locate two surviving Russian cosmonauts, who reveal satellite photos of hundreds of Pillars being stockpiled on the Moon. Sam realizes that the Decepticons raided the Ark long before the Autobots' mission and intentionally left Sentinel and five Pillars behind to lure the Autobots into a trap – Sentinel being the key to activating the Pillars and the Decepticons lacking the means to revive him. The Autobots rush to return Sentinel to their base for protection but Sentinel betrays them and kills the Autobot Ironhide, revealing he had made a deal with Megatron to ensure the survival of the Cybertronian race. Sentinel uses the Pillars to transport hundreds of concealed Decepticons from the Moon to Earth, and Carly is captured by Gould, who is revealed to be in the service of the Decepticons. The Autobots are exiled from Earth at the demand of the Decepticons to avoid war, but as their ship leaves Earth it is destroyed by Megatron's second-in-command, Starscream, seemingly killing the Autobots. The Decepticons, led by Megatron and Sentinel, seize Chicago as their agents place Pillars around the world. Gould reveals to Carly that the Decepticons plan to transport their homeworld of Cybertron to the Milky Way, then to enslave humanity and use Earth's resources to rebuild their world. Sam teams with USAF Chief Robert Epps to go into Chicago to save Carly, but they are nearly killed by Decepticon forces before the Autobots intervene, revealing they concealed themselves during the launch of their ship to convince the Decepticons they were destroyed.
