On Thursday, Dark Knight Rises director Christopher Nolan and Steel City first-timer Christian Bale held a Pittsburgh press conference to thank the city for hosting production on the final installment in the Batman trilogy. Nolan said that they chose Pittsburgh because "it is a very beautiful city on a very impressive scale and yet one which has a community that hasn't lost its human scale." So, not because of the Wiz Khalifa song "Black and Yellow"? Go figure. Filming begins tomorrow. Principal photography started in May. [Post-Gazette]
