As Variety reports, the venerable Swedish actor Max von Sydow—the list of credits for the actor is very long indeed—is taking over the “three-eyed raven” role originated in the fourth season by Struan Rodger. As Variety notes, much like the Ian McShane casting, this role is relatively brief in screen time, but it will be important—in his case, Sydow’s role will be described as a “major” one.
Given that Isaac Hempstead Wright has admitted he’d be back for season 6 after a 1 season hiatus, it looks like we’ll be seeing how Bran has gotten along beneath the weirwood with his new mentor.
