You guys crack me up! No one on this board has a freaking clue what it cost to actually make this movie. You want to question something question the mareting budget which was probably double the 18!
Let me tell you some facts. It cost and was budged for over he reported 180 million AND in the end Nolan brought it in UNDER budget.
I read some idiot here state that Chicago cost 17 million, are you high?
Try 90 million before tax credits given the film. They shot there on two separate occasions, one time for 7 days the other time for almost 2 months and that would include the crew , local and Brits, equipment including, props, cameras, and special rigs, (ultimate arm with its mercedes suv) 5 Batmobiles, 4 Batpods, so much more, traveling back and forth to London 2 times.
Hong Kong was a very minor part of the cost as they had a very small crew, a few principals, extras and rentals, shooting for something like 5 days, and NO stunts were performed there, except the plane over hong kong harbor, not really a stunt.
While CGI is limited, there is a lot more than the helicopter and the scene in Hong Kong, flying out of the window is all cgi, scenes in chicago evacuation, the ferries, a lot of miniatures. Just look at the credits people, that should give you a good indication of why these things cost what they do.
But who cares really, by the end of the week all of that initial cost of production will be recouped and they will start throwing money at Nolan to do a third, well lets hope so anyway.
