Misdirection for the Dragonpit Scene
Showrunners Benioff and Weiss were notoriously secretive about the show’s production, especially in the later seasons, in hopes of preventing leaks and spoilers. For the series finale Dragonpit scene when Bran is chosen as king, they went so far as to fly in actors to the set who weren’t even in the scene, like Tom Wlaschiha and Faye Marsay, who played Jaqen and the Waif, and Vladimir Furdik, who played the Night King, all in the name of misleading nosy fans about the scene’s true contents.
