Transformers is a 2007 live-action film adaptation of the Transformers franchise, directed by Michael Bay and written by Roberto Orci and Alex Kurtzman. It stars Shia LaBeouf as Sam Witwicky, a teenager involved in a war between the heroic Autobots and the evil Decepticons, two factions of alien robots who can disguise themselves by transforming into everyday machinery. The Decepticons desire control of the All Spark, the object that created their robotic race, with the intention of using it to build an army by giving life to the machines of Earth. Megan Fox, Josh Duhamel, Tyrese Gibson, Jon Voight, Anthony Anderson and John Turturro also star, while voice-actors Peter Cullen and Hugo Weaving voice Optimus Prime and Megatron respectively. Producers Don Murphy and Tom DeSanto developed the project in 2003, with a treatment written by DeSanto. Executive producer Steven Spielberg came on board the following year, hiring Roberto Orci and Alex Kurtzman. The United States Military and General Motors loaned vehicles and aircraft during filming, which saved money for the production and added realism to the battle scenes.

Hasbro organized an enormous promotional campaign for the film, making deals with hundreds of companies. This advertising blitz included a viral marketing campaign, coordinated releases of prequel comic books, toys and books, as well as product placement deals with GM and eBay. The film was a box office success despite mixed critical reaction to the radical redesigns of the characters, and reviews criticizing the focus on the humans at the expense of the robots. It is the thirty third most successful film released and the fifth most successful of 2007, grossing approximately US$709 million worldwide. The film won four awards from the Visual Effects Society and was nominated for three Academy Awards for Best Sound, Best Visual Effects, and Best Sound Editing. The film became the first in a series, it revitalized media interest in the franchise, and a sequel Transformers: Revenge of the Fallen was released on June 24, 2009. On October 1, 2009 a third movie in the series was announced for July 1, 2011.
