Transformers: Revenge of the Fallen is a 2009 American science fiction action film, directed by Michael Bay and produced by Steven Spielberg. It is the sequel to Transformers (2007) and the second film in the live action Transformers series. The plot resolves around Sam Witwicky (Shia LaBeouf), the human caught in the war between Autobots and Decepticons, having visions of Cybertronian symbols, getting hunted by the Decepticons under the orders of their long-trapped leader, The Fallen, who seeks revenge on Earth by finding and activating a machine that would provide the Decepticons with an energon source, destroying all life on the planet in the process.

With deadlines jeopardized by possible strikes by the Directors Guild of America and the Screen Actors Guild, Bay managed to finish the production on time with the help of previsualization and a scriptment by his writers Roberto Orci, Alex Kurtzman, and series newcomer Ehren Kruger. Shooting took place from May to November 2008.
