Yeah, I hope it's Talia. They should also find a way to "resurrect" Ra's.
Well, there's always the Lazarus Pit, but that doesn't seem right for the movie versions of the character. Still, that sounds like a fine idea.
Still, rather than one big villain, it could be a bunch of smaller ones (perhaps with the Penguin as a leader). Not necessarily going for a lot of villains per se (we know how that usually turns out) but to continue the idea that both Batman and Joker changed everything and that classic crime has been replaced by madmen (which was tackled in the Long Halloween mini-series). Scarecrow can come back in a small role. You don't have to give them all special attention but just to show that traditional crime is being supplanted by something most destructive and unsettling.
Or maybe bring in Hugo Strange but also give him elements of recent Bat-Villain Dr. Hurt who wants to break down Batman both physically and psychologically.
If they do the Joker again, I think it would work, but it will be a Hell of a job for the actor replacing Ledger.
You can call it any damn thing you please, I just ask two things: DO NOT HAVE A LOVE INTEREST, and do not have Catwoman in it (unless she gets the shit kicked out of her in three seconds flat, that would be awesome). The ultra serious Nolan version of Batman has already figured out he can't have a girlfriend without endangering her (something the audience figured out many years ago), and would have no problem punching a female villain. So a background plotting type villain like Harley Quinn or Talia, that's fine.
I'd like to see Harley Quinn in a live action film, though I can't think of any particular actress who would be the best choice to play her.
Me too. I think she'd be a good choice as she would be trying to free Joker from Arkham and she works mostly in the background, not a hand to hand combater. Maybe we only see the Joker in deep shadow and hear his voice a little.
I like Harley, but I don't think she belongs in the Nolan/Goyer version of Gotham. She's a little too straightforwardly comedic.
