Transformers 4 was filming on Lasalle St in downtown Chicago on September, 7 2013. The photos below were taken during pick-ups after the main pyro scene. Michael Bay (in white) directs Mark Wahlberg, Nicola Peltz, and Jack Reynor, who seem to be exiting a crashed flying vehicle of some sort. I managed to get a decent vantage point, but I wish I could have gotten closer. Of course security had everything locked down pretty good. I am not sure who the actor is that Whalberg is grabbing by the neck. I am sure I will have more shots in the next month. I still need a shot of Optimus!
