Hasbro's ever-popular toy franchise takes centre stage in Armageddon director Michael Bay's super-sized sci-fi action adventure. When teenager Sam Witwicky (Shia LaBeouf) buys a second-hand car, he soon finds out that it has a life of its own. As well as helping him get close to the girl of his dreams (Megan Fox), it draws him into the long-running war between the alien Autobots and their evil nemeses the Decepticons, which is now taking place on Earth. The film may be a robotic replay of (executive producer) Steven Spielberg's ET with elements from other popular fantasies grafted on, but the humorous high-octane thrills are never less than astonishing. Most impressive is the seamless integration of CGI animation into live action - and the sheer scope of its ambition. The conversion from cars and helicopters into enormously detailed iron giants in seconds is breathtaking. Despite a finale overloaded with spectacle and massive explosions, Transformers is that rare thing - a truly innovative blockbuster.

Young teenager Sam Witwicky becomes involved in the ancient struggle between two extraterrestrial factions of transforming robots – the heroic Autobots and the evil Decepticons. Sam holds the clue to unimaginable power and the Decepticons will stop at nothing to retrieve it.
