Right now, I'm conviced there is a 'big bad' villain in Ben Affleck's Batman that we don't know about yet. Afterall, the confirmed Deathstroke is a mercenary and you'd think someone is fronting his bill.
Well, we now know who isn't the other villain, probably, thanks to Sienna Miller. Fandango's Erik Davis tweeted out this tid bit from a meeting with Miller. It seems she is keen to play Selina Kyle, but has been told the character won't be appearing.
I actually think Miller could make a great Catwoman. She's defintely go the look. I hope soon we start finding out what is in the movie, rather than what isn't though.
