We're two months into filming as of yesterday, and there's finally news from the Vale. According to his CV, English actor Rupert Vansittart has been cast as Lord Yohn Royce on Game of Thrones.
Vansittart will be playing the head of House Royce, bannermen of House Arryn and loyal to Lady Lysa. The character is nicknamed "Bronze Yohn" in the books because of his bronze, rune-inscribed armor. Yohn is the father of Ser Waymar Royce, the young Night's Watchman who was killed by a White Walker in the first fifteen minutes of Game of Thrones' premiere episode.
