Christopher Nolan: The end of The Dark Knight left the characters in a pretty interesting place. Because were trying to make one unified story here, so its not another episode, another Batman episode, if you like. For me, that meant really trying to be true to where the characters were left. And Bruce Wayne, as Batman, has made a rather large sacrifice at the end of The Dark Knight. For that to mean something, he really has to have succeeded in a sense, in his mission. He has to have a Gotham that at least superficially doesnt need Batman anymore. And that leaves him frozen. And the eight year period is about showing that hes retired in a sense, that hes hung up his cape and his cowl. But he hasnt been able to move on, hes stuck.
