I think this might be top-heavy character-wise, but I wonder what it would take to portray the "modern" post-52 Bat-universe: Batman (Bruce) Nightwing Robin (Damian) Red Robin (Tim) Batwoman Batgirl (Barbara) Red Hood (Jason) If nothing else, the next "bat movie" should feel free to make a thematic jump from the Nolan-verse. Don't try to continue it. Don't bother with any origin tales, just jump into the action like it's already established. Go in another direction, just don't regress into camp. Use the Morrisonverse characters, especially the villains (avoid the Joker, for example), and bring him along as a producer-co-writer.
