According to the THR article, the list includes Biel, Knightley, Anne Hathaway (Princess Diaries), and Gemma Arterton (Clash of the Titans, Prince of Persia). Two lesser known actresses, Kate Mara (Entourage, We are Marshall) and Charlotte Riley (The Take) are also under consideration.
There are reportedly two major female roles in Dark Knight Rises to fill, including a romantic lead and possibly the role of Talia, the daughter of Batman Begins villain Ra’s Al Ghul who is reportedly appearing in the next film.
The dark horse in the race may be Riley, as she is engaged to actor Tom Hardy, who appeared in Christopher Nolan’s Inception and also has a small role in Dark Knight Rises.
Let’s hope Nolan leans away from a big name and goes with Mara or Riley. Arterton is seriously overexposed right now and the rest are just too well known to not stick out against Bale and company.
