Does Batman have his tie in feats?
Is that canon with the Nolanverse?
The producers said it's not necessarily canon since it can pretty much fit into any continuity.
Ya they say not necessarily but it's pretty much canon. They make direct references to events in Batman Begins like Scarecrow being on the run, Arkham Asylum being destroyed and the Narrows incidents and Gotham Knight even sets up events in the Dark Knight like Ramirez joining Gordon's unit and Batman and Jim cracking down on the mob making them desperate like we see them in Knight. David Goyer and John Nolan even worked on the story board for it and Nolan himself considers it a part of his universe.
