It's interesting that the press release only mentions Selina Kyle, of course Catwoman (even if not mentioned by name) will show up at one point. Actually that would be pretty cool if they don't call her Catwoman at all. Selina Kyle by day mysterious unnamed burglar by night?
The industry speculation or "rumors" going around when various actresses were reading with Bale were that Nolan was casting two roles for two different actresses. 1. The love interest in a Vicki Vale/Rachel Dawes sense and 2. The other was the villain Catwoman/Talia Al Ghul.
I much preferred the Catwoman angle to Talia. First I don't know much about her and with Liam Neeson's character not around, who cares?
Also who remembers the Halle Berry film? From what I can recall no one saw it. I sure didn't.
