context_page_description: Transformers is a 2007 American science fiction action film based on the Transformers toy line. 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 retrieve and use the AllSpark, the object that created their robotic race that is on Earth, 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.

Cullen had previously voiced Optimus Prime in the original 1980s cartoon and was chosen to reprise his role, which was warmly welcomed by audiences and considered one of the film's best aspects.
  Mark Ryan as Bumblebee, the Autobot scout and Sam's new guardian who transforms into a yellow and black Chevrolet Camaro (first a 1976 model and later in the movie a 2006 model).
  Darius McCrary as Jazz, Optimus's second-in-command who transforms into a silver 2006 Pontiac Solstice.

  Hugo Weaving as Megatron, the leader of the Decepticons who transforms into a silver Cybertronian jet.
