Alright so I have a theory on a Inception and the Dark Knight franchise... I believe that when the batman films take place that Leonardo Dicaprio was in a dream... Ok bare with me but I think Nolan is planning a crossover for both films. Look why is Leonardo Dicaprio's girl in TDKR or why is Bane in the film or even Scarecrow... Blake is in the film too... I think when Leonardo Dicaprio going off on his own dreams he was pretending to be Christian Bale in a Batman suit and that Leonardo Dicaprio thinks that his girl is a back stabbing women and Leonardo Dicaprio goes through a arc from Batman begins to The dark knight rises and he finally blocks out his girl but then lets her in. In the dark knight rises she changes but then backs stabs him :'( and almost kills him. It's clear Nolan loves twists... I believe this is one of them.
I think Warner Brothers is going make a film that ties it all together then make a Justice League movie.
