You hear that rumbling? It's the Transformers revving up for their next big-screen outing, in Michael Bay's Age of Extinction.

Ahead of the film's Friday premiere, Paramount Pictures has unleashed a series of new photos featuring the likes of Optimus Prime, Bumblebee, Grimlock, Drift and Hound, as well as Mark Wahlberg, Nicola Peltz, Jack Reynor, Stanley Tucci and Li Bingbing.

The film begins after an epic battle that left a great city torn, but with the world saved. As humanity picks up the pieces, a shadowy group reveals itself in an attempt to control the direction of history… while an ancient, powerful new menace sets Earth in its crosshairs. With help from a new cast of humans, Optimus Prime (voiced by Peter Cullen) and the Autobots rise to meet their most fearsome challenge yet. In an incredible adventure, they are swept up in a war of good and evil, ultimately leading to a climactic battle across the world.
