Michael Shannon contender for SUPERMAN villain?

Earlier we reported that Edgar Ramierez was rumored to be up for the villain role in Superman: Man of Steel for Warner Bros. Deadline reports that Zack Snyder and Legendary Pictures are considering Michael Shannon for the role. He had a great first season in HBO's Boardwalk Empire, and a strong performance in Take Shelter (Read our review here). Fans will soon be able to seek Shelter,  thanks to Sony Pictures Classics acquisition at Sundance. Just like the Ramirez story, the studio nor Shannon's reps could confirm the story. 

I think that Shannon is amazing in Boardwalk Empire and think he would make a great villain. What are your thoughts?
