Also, The Riddler will NOT be the villain.
For anyone who has followed Nolan's comments, this should be of no surprise. I still think Riddler could fit well into this series (what I keep imagining is something closer to the Zodiac killer, but still), but I'm curious to see who else he comes up with.
While the Joker stole the show in the second film, the film was about Bruce Wayne (and even Harvey Dent) more. Casting the Riddler could make the series too villain-centric.
Dark Knight Rises could work. I could also have seen something with Redemption in it.
