LOS ANGELES (TheWrap.com) - Could the feds be preparing to close in on Nucky Thompson?
Eric Ladin - aka, campaign manager Jamie Wright on the AMC drama "The Killing" - has been cast in the upcoming fourth season of HBO's period gangster drama, starring Steve Buscemi as Atlantic City kingpin Thompson.
Ladin will play FBI director J. Edgar Hoover - an addition to the show that just might prove to be problematic to Thompson as he attempts to strengthen his position in the world of organized crime.
The HBO drama has been bolstering its cast for the fourth season. "Casino Royale" actor Jeffrey Wright has been cast as Harlem kingpin Valentin Narcisse, while Ron Livingston has signed on for the season as Roy Philips, who comes to town and captures the fancy of Gillian Darmody (Gretchen Mol).
In addition to the upcoming stint on "Boardwalk Empire," Ladin also has a role in the dramedy "Highland Park," which stars Danny Glover, "Twilight" alum Billy Burke and Parker Posey.
