i just re-read the graphic novel not too long ago. really hyped for this now:
some background:
- this takes place several years after batman has retired (...sound familiar
- in part 1 harvey dent, after receiving cosmetic surgery, relapses as two face and brings an old-aged batman out of retirement
- he teams up with a gymnast girl who discovers his identity and takes on the robin mantle (familiar again

... no mention/appearance of nightwing.
- in part 2, batman has to fight a gang leader who has overrun gotham city with his band of goons and mercenaries (hmmmmm....)
- gotham is under a nuclear threat (... i think i saw a movie like this)
if you were fan of TDKR, i'd say check this out as it (graphic novel) is definitely one primary sources of inspiration for the nolan films.
there's even a part when Batman first re-appears, and an old cop tells a rookie cop "it's Batman! hey, you're in for a show!"
