Transformers is a 2007 American science fiction action film based on the toy line of the same name created by Hasbro. The film, which combines computer animation with live-action filming, was directed by Michael Bay, with Steven Spielberg serving as executive producer. It was produced by Don Murphy and Tom DeSanto, and is the first installment in the live-action Transformers film series. The film stars Shia LaBeouf as Sam Witwicky, a teenager who gets caught up in a war between the heroic Autobots and the villainous Decepticons, two factions of alien robots who can disguise themselves by transforming into everyday machinery, primarily vehicles. The Autobots intend to use the AllSpark, the object that created their robotic race, to rebuild their home planet Cybertron and end the war, while the Decepticons have the intention of using it to build an army by giving life to the machines of Earth. Tyrese Gibson, Josh Duhamel, Anthony Anderson, Megan Fox, Rachael Taylor, John Turturro, and Jon Voight also star, while voice actors Peter Cullen and Hugo Weaving voice Optimus Prime and Megatron respectively.
Murphy and DeSanto developed the project in 2003, and DeSanto wrote a treatment. Steven Spielberg came on board the following year, hiring Roberto Orci and Alex Kurtzman to write the screenplay. The U.S. Armed Forces and General Motors (GM) loaned vehicles and aircraft during filming, which saved money for the production and added realism to the battle scenes. Hasbro's promotional campaign for the film included deals with various companies; advertising included a viral marketing campaign, coordinated releases of prequel comic books, toys, and books, as well as product placement deals with companies such as GM, Burger King, and eBay.
Transformers received mixed to positive reviews from critics and fans. It is the 87th highest-grossing film of all-time and was the fifth highest-grossing film of 2007, grossing $709 million worldwide, with an estimated 46 million tickets sold in the US. The film won four awards from the Visual Effects Society and was nominated for three Academy Awards, for Best Sound Editing, Best Sound Mixing, and Best Visual Effects. LaBeouf's performance was praised by Empire, and Cullen's reprisal of Optimus Prime from the 1980s television series was well received by fans. It was soon followed by four sequels and a prequel: Revenge of the Fallen (2009), Dark of the Moon (2011), and Age of Extinction (2014), the later two of which grossed $1 billion. A fifth installment, titled The Last Knight, was released on June 21, 2017, with Bumblebee: The Movie serving as both a spin-off and aforementioned prequel to the film will release on December 21, 2018.
