Barry Sloane, the actor behind Captain John Price in the Call of Duty: Modern Warfare games, has joined House of the Dragon's cast. Season 3 episode 4 quietly revealed that he plays Ser Adrian Redfort, the newest addition to Queen Rhaenyra Targaryen's Queensguard. Redfort comes from an old noble family in the Vale of Arryn and steps in as a loyal protector during the Dance of the Dragons. Fans will likely recognize Sloane's voice before his face, since his Price performance in Modern Warfare (2019) earned him a BAFTA Games Award nomination, and he's reprised the role in every mainline entry since, including the upcoming Modern Warfare 4. Given hints Sloane's dropped about a "dangerous side mission" and comments suggesting his time on the show may already be winding down, Redfort might not be sticking around Westeros for long. Either way, it's a fun crossover moment for anyone who's spent years taking orders from Price in-game and now sees him picking up a sword in Westeros instead....
