If, as Jon Favreau has suggested, this summer really does turn out to be a blockbuster bloodbath, no one will accuse Michael Bay of not having brought all he can to the fight with Transformers: Dark of the Moon. On the evidence of this first full trailer, he’s loaded up enough robo-crunching, building-destroying, Shia LaBeouf-endangering action to keep fans of the franchise buzzing. Check it out over at Apple.

While it’s impossible to judge whether this third TF pic will keep Bay’s promise of a more streamlined story and less messy/stupid plotting from a promo, that’s not what trailers are really about.

But there are hints of the plot within here, as Frances McDormand’s government wonk risks the wrath of Optimus and the Autobots by finally revealing something that might have been handy to let slip before – astronauts exploring the Moon discovered a crashed Cybertronian spacecraft. Despite the fact that the conflict between Optimus’ crew and the evil Decepticons has long since been brought to Earth, the US government decided not to mention this vaguely important discovery. But when the Decepticons launch an all-out offensive, targeting Chicago, things change quickly.

From the looks of this, loyalties will be tested, massive destruction will be caused and Sam will try to save new girlfriend Carly (especially since she looks like Rosie-Huntington-Whitely). Oh, and we’ll see a behemoth Decepticon and meet Sentinel Prime (who’ll sound like Leonard Nimoy). WATCH TRAILER
