‘Game of Thrones’ Brings In Oscar Winner Jim Broadbent for Season 7

Jim Broadbent, a real-life Oscar winner and Harry Potter alum, is joining the cast of Game of Thrones for a top-secret role in Season 7.

According to Variety, HBO has confirmed that Broadbent’s role will be “significant,” but will not offer any other details. Since the TV show has moved past the George R.R. Martin books, diehard fans are left wondering who, exactly, Broadbent will play, much like they did last season with Ian McShane’s one-episode appearance.
