Re: How long did Nolans Batman actually fight crime?(SPOILERS)
So with this new information it seems like Nolan decided to use the most essential parts of Bruces journey as the Batman. Between his first appearance where he caught Falcone and the train fight with Ras, that's a year or two of unseen stories. Between Ras and Joker it's another 3 years. Then X amount of months during Rises. 5 to 6 years as the Batman. During the span of 13 or 14 years.
That surely beats the hell out of a year and a half, which is what the world is thinking at the moment.
