As shared by Empire, The Nolan brothers utilized their experiences creating other films, namely “The Prestige” and “Inception,” to better build “The Dark Knight” trilogy. For starters, Jonah Nolan expressed a thematic deviation from “Batman Begins” to “The Dark Knight” that found its roots in “The Prestige,” where Nolan found that moving his crew around from location to location envigorated them creatively. Nolan shared how he took that approach to “The Dark Knight”:
“When we made ‘The Dark Knight’ we quite specifically moved around. We started in Chicago, went to London, went back to Chicago which is a massive production no-no; you’re never supposed to go back to the same place. But it meant we constantly challenged people to work in a new environment on a daily basis.”
When you’re sporting the kind of budget that a Nolan film is (in the case of “The Dark Knight,” just a little under $200 million, by the way), you’ve got the wiggle room to make a few extra flights across the globe to get those creative juices flowing.
