EW says

Last night’s episode of Boardwalk Empire marked a pivotal turning point for lawman Nelson Van Alden, who has spent the first half of this season trying to keep his baby mama Lucy a secret from his loving wife (to say nothing of his fellow Prohibition agents). We talked to actor Michael Shannon — currently in the midst of a busy year that includes the recent release of the lauded Take Shelter and production on 2013′s Superman reboot Man of Steel — about the big developments in last night’s episode. (As a bonus, he talked a little bit about taking over for Terence Stamp as General Zod, too!) (Boardwalk Empire, Cinema, Man of Steel, Michael Shannon)
