Ah so that explains DeNiro.
That's great news about it being stand alone.
I wouldn't mind it being integrated into a Batman reboot, if they managed to create a Batman that fit this down-to-Earth style (in fact, that'd be kind of interesting) but beyond that, when you start to throw in every Batman villain, let alone Justice League stuff, it just becomes a farce.
On that note, i was wondering if they could write a Spiderman reboot, where Spiderman is the only superhuman character (no super villains at all) and have a story like that.
I think that could be an interesting take.
