Transformers: Revenge of the Fallen is a 2009 American science fiction action film based on Hasbro's Transformers toy line. The film is the second installment in the Transformers film series and the sequel to Transformers (2007). The film is directed by Michael Bay and written by Ehren Kruger, Roberto Orci, and Alex Kurtzman. Taking place two years after the previous film, the story revolves around Optimus Prime (voiced by Peter Cullen), leader of the Autobots, and Sam Witwicky (Shia LaBeouf), who is caught once again in the war between the Autobots and the Decepticons, led by Megatron (voiced by Hugo Weaving). Sam begins having strange visions of Cybertronian symbols, and is being hunted by the Decepticons under the orders of an ancient Decepticon named the Fallen (voiced by Tony Todd), who seeks to get revenge on Earth by finding and activating a machine that would provide the Decepticons with an energon source, destroying the Sun and all life on Earth 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. Shooting took place between May and September 2008, with locations in Egypt, Jordan, Pennsylvania, New Jersey, and California, as well as air bases in New Mexico and Arizona. It is the last film in the series to star Megan Fox. Transformers: Revenge of the Fallen premiered on June 8, 2009 in Tokyo and was released on June 24 in the United States. The film received generally negative reviews from critics. The film won three Golden Raspberry Awards at the 30th Golden Raspberry Awards ceremony and became the highest-grossing film to win the Worst Picture award. Nonetheless, the film surpassed its predecessor's box office gross worldwide with $836.3 million, making it the fourth-highest-grossing film of 2009. With over 11 million home media sales in 2009, it was also the top-selling film of the year in the United States. It was followed by Transformers: Dark of the Moon in 2011.
