After setting Henry Cavill for the lead role, and Diane Lane and Kevin Costner for Ma and Pa Kent, Warner Bros., Legendary Pictures and director Zack Snyder are working on a villain for Superman: Man of Steel. I’m told there’s interest in Michael Shannon. Shannon is coming off a memorable first season in HBO’s Boardwalk Empire, and he turned in a strong performance in Take Shelter, which Sony Pictures Classics acquired at the 2011 Sundance Film Festival. Neither the studio nor Shannon’s reps were helpful.
