20 Behind-the-Scenes Secrets from The Dark Knight
An IMAX Camera Was Destroyed on Set
One of the reasons The Dark Knight was the first movie to film with IMAX cameras is that they are incredibly big and incredibly expensive. Breaking one at the time would have been a fairly big deal, in part because there were only a few in existence.
Apparently, that’s just what happened on the set of The Dark Knight when the crew was filming the SWAT team chasing after the Joker. Most of the time, stunts look more dangerous than they actually are. In this case, though, there was definitely some real damage done as a result of some on-screen action.
