EXCLUSIVE: Moneyball helmer Bennett Miller is putting together the final casting pieces for Foxcatcher, the Annapurna Pictures-funded drama that stars Steve Carell as paranoid schizophrenic heir Jon DuPont, who created a training center for wrestlers and murdered Olympic grappler Dave Schultz. That wrestler will be played by Mark Ruffalo, and Sienna Miller will play his wife, Nancy. Channing Tatum is playing Schultz’s brother, Mark, in the tragic tale.
