The Transformers Movie is a 2007 live action science fiction film conceptually based on the Transformers franchise and toy line. The film is directed by Michael Bay with Steven Spielberg acting as the executive producer. The film stars Shia LaBeouf as Sam Witwicky who discovers the map to the Allspark, the source of life which the heroic Autobots and evil Decepticons wage a war over. The project originated with producers Don Murphy and Tom DeSanto, who gained support from fans on the Internet to rehire Peter Cullen as the voice of Autobot leader Optimus Prime, 20 years since the original cartoon ended. This adaptation is the Transformers’ first American feature film since The Transformers: The Movie in 1986. However, this film is intended to be a reboot of the franchise, with a new complex design aesthetic for the Transformers.
