After an upraising he himself describes as "hippie", Shia laboeuf made his debut on the Disney Channel show Even Stevens. Since then he's gone on to appear in films including Constantine and A Guide To Recognising Your Saints, as well as upcoming thriller Disturbia and penguin-centred animation Surf's Up. In Transformers, he's plays a young lad lucky enough to buy a Transformer as his first car.

Josh Duhamel started out in TV, including US soap epic All My Children and glitzy drama Las Vegas. He's made the transition to film with parts in Win a Date With Tad Hamilton and Paradise Lost. Here, he plays an army officer who gets on the wrong side of the Decepticons. BBC Movies' Tae Mawson asked them both all about the film.
