Stephen Root Cast on Boardwalk Empire As...

In his ever-evolving quest to appear on every primetime show on television, Stephen Root has signed on to Boardwalk Empire.

The actor (NewsRadio, Justified, True Blood, Fringe, The Good Wife) will recur next season as Gaston Means, an ex-murder suspect who is now a Special Investigator for the United States Department of Justice under Attorney General Harry Daugherty.

Root will pop up on multiple episodes of the HBO drama, while Bobby Cannavale will come on board as a series regular, playing a gangster rival to Nucky.
