Just yesterday production began on what will be director Christopher Nolan’s final film in his Batman trilogy: The Dark Knight Rises. Today, the viral campaign for the film kicked off, giving us our first look at Tom Hardy as Bane, and now two more actors have been added to the cast. Variety reports that Matthew Modine and Tom Conti have signed on to the film. With the plot under lock and key, there’s no word on who the two actors will be playing. However, since this is Batman and every piece of news is greeted with fanfare, I wouldn’t be surprised if the two play fairly minor roles. Nolan similarly cast known actors in smaller parts for the last two Batman flicks (Anthony Michael Hall, Rutger Hauer, etc.).The Dark Knight Rises also stars Christian Bale, Anne Hathaway, Joseph Gordon-Levitt, Marion Cotillard, Morgan Freeman, Gary Oldman, and Michael Caine.  It opens July 20, 2012.[Update: Variety's story has been updated to say that 11-year-old Joey King (Ramona and Beezus) has joined the cast as well]
