The official Twitter feed for Michael Bay has posted a dynamic behind-the-scenes photo of the filmmaker hard at work on the set of Transformers: Age of Extinction. Of course, it isn't exactly clear what is being filmed, but the crew member seen spraying debris from a hose likely indicates there is some explosive action at hand. Take a look at the photo, and stay tuned for more images from the set as production continues.
