Starting today Transformers 4 production hits Detroit, Michigan starting at the China set location that has been under construction for over a month Taking advantage of the People Mover that goes nearly through the set, below is a video that gives you a nice view of the set. I am not entirely sure but I think the location is really three or more sets combined. One section looks like a Chinese village, another like a shopping center (or mall facade, not really sure), and another might fit near shipping docks with a cave structure built out of cargo containers.
