It is reported that Liam Neeson might have bagged a guest appearance in the new Batman film. He is rumoured to be starring once again as Ra"s al Ghul, Bruce Wayne"s mentor and nemesis, even though he appeared to die at the end of Batman Begins. It is speculated that Talia al Ghul, Ra's daughter, brings him to Lazarus Pit to resurrect him after his battle against Batman.
Josh Pence has already been confirmed to reprise the role of a young Ra"s al Ghul, while Marion Cotillard is rumoured to be playing the part of the villain"s estranged daughter, Talia al Ghul. But when asked about the role, Warner Bros refused to comment saying “It was simply not policy when it comes to the Batman films that Christopher Nolan and company make."
