The new still comes just a few days after Bay shared a snap of himself behind the camera, apparently filming an action scene on the fourth instalment of the toy-based movie franchise.

Bay has previously revealed that the new film will not follow the action from the previous three movies - but will be a "standalone" offering.

It is expected to feature the Dinobots, and has been scheduled for release on 7 July, 2014, in the UK.
