Transformers: Dark of the Moon (2011)

In 1961, the Ark, a Cybertronian spacecraft carrying an invention capable of ending the war between the benevolent 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 spacecraft. In 1969, the crew of Apollo 11 lands on the Moon and secretly inspect the Ark before heading home. President Richard Nixon orders them to keep the details of this mission secret.

In the present day, three years after the Battle of Egypt, the Autobots assist the United States military in preventing major conflicts around the globe. During a mission to Chernobyl, Ukraine (site of the 1986 Chernobyl nuclear disaster) to investigate suspected alien technology, the Autobots are attacked by Decepticon scientist Shockwave and his giant worm Driller. After the two escape, Optimus Prime finds the technology is a fuel cell from the Ark, discovering it had survived its escape from Cybertron. 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’s predecessor as leader of the Autobots—and five 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.
