In addition to a latest Autobot to appear in Michael Bay’s Transformers 4, we get a first look at Mark Wahlberg on set of the new film. It looks like Wahlberg has kept in shape from his previous collaboration with Bay (Pain and Gain) and has brought along some vintage vehicles for the latest Transformers installment. We get looks at an old Chevy pick-up, a rusted-out big rig and a throwback firetruck from these images taken on set in Texas. There’s no indication of whether these autos are robots in disguise or merely good old fashioned set dressing, but a new vehicle from Bay’s blog will surely be doing some transformin’. Which Autobot it may be is anyone’s guess. Hit the jump to check it out.
