Mark Wahlberg On Set Of Transformers 4
Star looks mean and moody in still from forthcoming movie sequel...
DirectorMark Wahlberg standing in the desert looking moody, with an abandoned petrol station and co-stars Nicola Peltz and Jack Reynor behind him.
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.
