Michael Bay is known for his CGI action sequences, but based on a new behind-the-scenes clip from Transformers: Dark of the Moon, it looks like this time around the director aims to thrill us with something REAL. Something that's making us feel a little queasy.
We've already seen a clip of the film's stars falling through the sky in wingsuits, and of course figured many of the stunts there were accomplished through FX fakery. But a new clip reveals that Bay actually hired a group of daredevils to leap off Chicago's Sears Tower for REAL.
Check out the insanity below, and try not to get too dizzy.
