Casting news has been trickling in, including a first glimpse of the new character, The Mountain, played by Hafþór Júlíus Björnsson. According to the Huffington Post, "Björnsson will play Gregor "The Mountain" Clegane, The Hound's brutal brother. The Icelandic native is the third actor to be cast in the violent role, after two men were recast in Seasons 1 and 2." The actor revealed himself as The Mountain in of all places, Instagram, but we think that sweet smile is deceiving.
