Nolan 'searching for Batman leading lady'

Christopher Nolan has allegedly started meeting potential leading ladies to star opposite Christian Bale in his latest Batman movie.

According to Moviehole, the Dark Knight director is looking for actresses in their late 20s and early 30s to take on the main female role in the superhero sequel.

Nolan and Warner Bros are keeping the casting under wraps, although insiders believe that the actresses could be meeting for the part of Catwoman.

"Some of the beauties coming in to chat with Christopher would suggest that," a source reportedly said.

Christian Bale and Sir Michael Caine will reprise their roles, while Nolan's Inception star Tom Hardy has been cast as the villain.
