With production looming closer, director Christopher Nolan has added a trio of actors to The Dark Knight Rises. Daniel Sunjata (TVâs Rescue Me), Diego Klattenhoff (Lucky Number Slevin), and Burn Gorman (Layer Cake) are all looking to join a cast that now includes Christian Bale, Michael Caine, Morgan Freeman, Gary Oldman, Anne Hathaway, Tom Hardy, Joseph Gordon-Levitt, Juno Temple and recent addition Josh Pence, who will take on the role of young Raâs al Ghul.Variety reports that Sunjata is in talks to play âa courageous special forces operativeâ and Klattenhoff is being offered the part of âa rookie cop who is looking to make a difference.â No word on who Gorman will play other than the fact that heâs being eyed for a supporting role in the film. Marion Cotillard was previously âin discussionsâ for a role in the film, but the report claims sheâs now officially part of the cast. Hit the jump for more.While the cast of The Dark Knight Rises seems like itâs growing every day, Nolan fleshed out nearly every supporting role in The Dark Knight and Batman Begins with fairly well-known/recognizable actors, so donât be alarmed by the amount of casting news being reported for the film (this is Batman after all, so expect many more stories to come). Nolan directs from a script that he co-wrote with his brother, Jonathan, and is producing the film alongside Emma Thomas and Charles Roven. The Dark Knight Rises starts shooting in Pittsburgh this summer for a July 20th, 2012 release date.
