The Transformers franchise is one that has grossed over $1 billion at the global box office in recent years.

And while the second movie was no a hit with the critics it certainly had cinema tills ringing two years ago.

This summer sees Michael Bay return to the director’s chair for Transformers: Dark Side of the Moon – which also sees Shia LaBeouf return to the franchise.

The Autobots Bumblebee, Ratchet, Ironhide and Sideswipe led by Optimus Prime, are back in action, taking on the evil Decepticons, who are determined to avenge their defeat in 2009′s Transformers: Revenge of the Fallen.

In this new movie, the Autobots and Decepticons become involved in a perilous space race between the U.S. and Russia, and once again human Sam Witwicky has to come to the aid of his robot friends.

There’s new characters too, including a new villain in the form of Shockwave, a longtime Transformers character who rules Cybertron while the Autobots and Decepticons battle it out on Earth.

Take a look at a new clip from the movie:
