According to the New York Times, director Michael Bay got creative with stunts in the flick. In one scene, paratroopers fight the Decepticons and do some BASE jumping from the hotel. Here, that means that three parachutists (and one computer-generated one) leapt from the Trump across the Chicago River. That isn't a small feat, given the stainless steel and iridescent-tinted glass building is 92 stories high.
We smell a possible new "Tranformers" adventure package that the Trump can offer. Maybe a zipline off of the hotel's facade? We'd totally sign up if Josh Duhamel was there as our partner paratrooper.
