The Transformers 4 shoot is definitely getting intense.
This week the Michael Bay-directed flick was in Chicago, shooting outdoors at McCormick Place and MIllennium Park and giving bystanders an opportunity to catch a nice piece of the action. There don't seem to be any spoilers among these brief videos, but there are some very cool explosions, panicked crowds and what look like propaganda posters reminding us never to forget the invasion of Chicago from Transformers: Dark of the Moon, not to mention a nice look at the big Autobot himself, Optimus Prime.
We've placed the most explosive of these videos above for your viewing pleasure, and you can check out three more below.
