Combining computer animation with live-action filming, with plenty of explosions and lens flare to excuse the awkward humour, Transformers is a true blockbuster. Directed by Michael Bay, Transformers is based on the franchise of the same name. Rewind to 2007 as this science fiction action film turns 15 years old. Sam Witwicky (Shia LaBeouf) is 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 powerful artefact 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.
