I wouldn't be surprised if Warner Bros does consider him for the Batman reboot if he does end up turning down "Justice League". He has become one of their go to directors lately.
TDKR hasn't even been out 2 weeks and people are already thinking about the reboot? Where's the respect for Nolan?
You're as good as your latest movie. TDKR is fun, but it doesn't make a lick of sense and most people are rather disappointed in it. He missed making a legendary trilogy by one movie so...
(I'm sure he'll cry himself all the way to the bank.)
