TNT's Agent X Adds to Cast

A few weeks ago we learned that Sharon Stone would topline TNT's spy pilot Agent X playing a newly minted U.S. Vice President who discovers that her job comes with a top secret sideline: protecting the Constitution in times of great crisis with the aid of her Chief Steward and a secret operative designated 'Agent X.' Now the cable network has rounded out the cast, filling the other leads—some with notable spy veterans. According to Deadline, Jeff Hephner (Chicago Fire) will play the title role of John Case, codenamed Agent X. Gerald McRaney (who even managed to be awesome in the lackluster Undercovers, his last spy series) will play Malcolm Millar, "the refined Chief Steward of the Vice President’s mansion, and keeper of its many secrets." (Her Alfred?) Homeland's Jamey Sheridan will play FBI Director Stanton, who's described as "patronizing and disdainful" towards the VP. (Perhaps he's just resentful, since he himself held that office on his last spy show.) The trade blog also reports that Mike Colter (Zero Dark Thirty, Salt) will play the Speaker of the House, tasked with oversight of the ultra secretive Agent X project, and (in a separate story) that Peter O'Fallon (Leverage, House) will direct the pilot.
