Moneyball director Bennett Miller is filling out the rest of his cast for the drama Foxcatcher, and now Sienna Miller has jumped onboard.  The film tells the true story of John du Pont, a paranoid schizophrenic who built a wrestling training facility on his 800-acre Pennsylvania estate where he subsequently shot and killed Olympic gold medal-winning wrestler David Schultz in 1996. Heir to his family’s chemical fortune, du Pont locked himself in his mansion for two days after murdering his friend, and spent the time on the phone with negotiators.

Steve Carell is set as du Pont, Mark Ruffalo is portraying Schultz, and Deadline reports that Miller will play Schultz’s wife.  Channing Tatum is also set as Schultz’s brother.  As a huge fan of Miller’s Capote and Moneyball, I’m really excited by the impressive cast he’s put together for Foxcatcher and look forward to seeing the finished film.  Production is set to begin later this year.
