Damn, I think there's some mileage in that idea. And I love that original book. Hopefully Nolan will show some imagination, I was surprised when he used the Scarecrow character.
I'd love it to be based on the Arkham Asylum comic, in that the Joker would draw Batman in to the nuthouse to face his demons. It would mean they could allude to a lot of classic enemies, get a really terrifying atmosphere brooding and maybe show a couple of them in the shadows. Then Bane could show up and break Batman. Batman should definitely die.
It's a great idea, but sadly they'd never make a film like that. The previous two are just too big, action packed blockbusterish.
I remember after The Dark Knight came out someone was saying that they'd love the third one to be really hallucinatory and crazy as it tracks Batmans mental state degrading. Like a David Lynch Batman movie, that'd be fucking awesome but it'd never happen either.
The Dark Knight Rises isn't a great name, but I can see why they'd keep the Dark Knight thing, as it was a departure from Batman Begins in that it was even more down to Earth (sorta). It was more grimy really, with gangsters and more gunplay, even down to the city aesthetically being different, featuring bland office buildings as opposed to the fantastical Gotham shown in Batman Begins. It was a good look that really worked, so I imagine Rises will have a similar aesthetic.
Anyway, this thread made me order Arkham Asylum, Year One, The Dark Knight Returns and the Killing Joke as I've heard so much about them. Hopefully they'll be delivered tomorrow.
