Rufus Sewell calls Allison Janney 'the perfect addition' to 'The Diplomat'

(SPOILER ALERT) The second season of Netflix's The Diplomat returns on Thursday, and while Rufus Sewell's character, Hal Wyler, was the victim of a car bombing at the end of season 1, he is indeed back for another go-round.

Former The West Wing star Allison Janney joins the cast in season 2 as Vice President Grace Penn, and Sewell calls her the perfect addition to the show.
