Last night at the MTV Movie Awards Michael Bay promised shooting on Transformers 2 would begin Monday, and he was as good as his word. We’ve got photographic evidence.

Tonight we got photos from a scooper, straight from the set of Transformers 2. They’re filming in Bethlehem, Pennsylvania at the Bethlehem Steel Plant, and apparently they’ve convinced the military to loan them a few attack helicopters. It’s hard to tell what they’re really up to from these pictures, but whatever it is, it looks expensive. Actually, the steel plant bears some resemblance to the factory where Shia LaBeouf was first chased by Barricade.

Check out what Michael Bay and Optimus Prime were up to on their first day of shooting Transformers 2, by checking out all of our set photos in the gallery below:
