I really hope Miranda Tate isn't Talia. That'd be a direct repeat of Ducard turning out to be Ra's. Instead of a Lazarus Pit, we just have the al Ghul family pretending to be other people? No thanks. Still, I understand the speculation since Hollywood Reporter kept saying Talia could be part of the film and we already know that Ra's will play a role (though only confirmed in flashbacks with Josh Pence). I just hope this isn't the case.
While I was also disappointed that Levitt isn't a comic book character, I'm glad he's not Alberto Falcone either, as Variety first reported. I hated the idea of bringing in the never-mentioned children of the villains from the first movie. I don't see how the Holiday story would fit with a story with Bane and Catwoman and, even if they didn't use him as Holiday, why have Alberto in it at all? I was relieved to find that he was playing a cop instead, even though I'd prefer to see Bullock (played by an older, gruff actor) as Dark Knight Rises's new cop character.
