According to Reports, it will take a lot of effort for Warner Bros to get Christopher Nolan to do a third Batman film. The site reports that the death of Heath Ledger rocked Nolan, and since the Joker was to be the villain in the third film as well, Nolan felt that The Dark Knight would be all for himself and Batman on film. Warner Bros. has apparently already put together a list of possible replacements for Nolan just in case Nolan doesn’t return. Some have reported that Nolan, along with Jonathan Nolan
and David Goyer, are currently developing ideas for another film, but if that even if that were to happen, it would not hit the big screen until 2012 at the earliest, with 2013 being more realistic.
