The Dark Knight - [spoilers ahead, ye be warned]

Another assist to TDK in beating Titanic in raw domestic box office is the fact that ticket prices are about 50% higher than they were in 1997 ($4.59 to $6.88). Box Office Mojo says the 2008 average ticket price is $7.08, but I don't know where they get their numbers.

So, $600 million in 1997 equals about 130 million buts in seats. For TDK it is only 87.2 million (84.7 million using Box Office Mojo's average ticket price).

Adjusting for Ticket Price Inflation (the number for TDK to beat to surpass Titanic is $908 million, though it is no longer the top film by that method)
