Bruce's final sacrifice was so poignant that I think it would be cool if Nolan pulled a "Blade Runner" and released a second version of the movie where he doesn't go off with his girl (like the original BR) but instead have the movie end with him dying. I get why he lived, and it was totally "Batman" for him to have a contingency but there's something about the hero who goes down with the ship to ensure victory. I'm looking at you Cap.
Has Nolan announced how the Joker was originally planned to play in TDKR? Was he supposed to more or less fulfill Bane's role or would they have gone in a totally direction entirely from the plot that we ended up with?
novel;
“Now that the Dent Act had made it all but impossible for the city’s criminals to cop an insanity plea, it (Blackgate Prison) had replaced Arkham Asylum as a preferred location for imprisoning both convicted and suspected felons. The worst of the worst were sent here, except for the Joker, who, rumor had it, was locked away as Arkham’s sole remaining inmate. Or perhaps he had escaped. Nobody was really sure. Not even Selina.”
