According to the article, Josh Pence from "The Social Network" has been cast as a younger Ra's Al Ghul, the role that legendary actor Liam Neeson played in a surprisingly awesome capacity in the first film by disguising himself as Ducard and misleading Bruce Wayne into thinking Ken Watanabe was Ra's until the final parts of the movie. While the end of Batman Begins suggests that Ra's perished in the climactic battle for the fate of Gotham City, his character will be making a return via flashbacks set some 30 years earlier to what takes place in "The Dark Knight Rises". Many rumors suggest that Inception actress Marion Cotillard may play Talia Al Ghul, the daughter of Ra's, but that hasn't been confirmed yet, nor is the other rumor that Neeson may return to reprise his role as Bat's greatest mentor/ enemy. We'll just have to wait and see how this fans out in the coming months. The movie starts shooting in May, so we'll probably get more news by then.
