I feel like I've already said this a million times, but I have to every time it's brought up. I can't help myself. I really really really
hope there's no Harley Quinn, and I'm pretty sure there won't be since apparently Nolan once laughed at the suggestion. I love Harley. I wear a shirt with her on it proudly and she's my favourite character in the animated series, but she works best as a cartoon character and I don't think she should ever be depicted otherwise.
I'm rooting for Talia. Great character and never done in live action before. I wouldn't mind seeing Catwoman again, but I love the Julie Newmar and Michelle Pfieffer versions so much, I don't think the world necessarily needs another one. Talia and a male villain would be enough. If one actress is Talia and the second female cast is the love interest, I won't be too disappointed by the lack of Catwoman. I just can't imagine Nolan having a character named 'Catwoman' in one of his movies. Sounds too silly.
