From the quite reliable MovieHole.Net comes this nugget of information.
Several young (“Late 20′s, early 30′s”) ladies are meeting with the Caped Crusader’s resuscitator this week to talk about the new film. Interestingly enough, quite a few of the ladies don’t actually know what role they’re being asked to read for/meet Nolan about (yep, security is tighter on this thing than the department store Jonathan Switcher worked at in “Mannequin” – Okay, maybe a bit tighter than that) they’ve just accepted an offer to “meet” with the filmmaker. Presumably, they’ll leave the meeting knowing quite a bit more.
I’ve the names of a couple of the young ladies meeting with Nolan, but I’ve checked in with them and they’ve kindly asked me not to name them – at least until they’re convinced they haven’t got the job (fair enough, don’t want to jinx it for anyone).
What I can say is that Nolan is open to casting a fresh face as the female lead; he’s not necessarily bringing in the big guns.
Hardly news, one might say. Almost every movie has a female lead that will be cast at some point during pre-production. Christopher Nolan is as expected keeping mum, but that doesn't stop us from speculating who the lead female role will be.
Could it be Julie Madison, Vicki Vale, Selina Kyle, Talia Al Ghul? It'll be months till we know for sure, but judging by Nolan's previous casting trends, the fact that Nolan isn't going after
name actors makes a female villain seem less likely.
