Game of Thrones has only aired three seasons and the series has already gone through two Mountains, with actor #3 on board to tackle the role for season four. 6’9″ Hafþór Júlíus Björnsson will be playing Gregor Clegane (aka The Mountain) when the HBO series returns for the fourth season, following in the footsteps of actors Ian Whyte and Conan Stevens.
The physically imposing character wasn’t seen in season three, however, Stevens played him in season one while Whyte handled the role in season two.
So how will the new Mountain look? Hafþór Júlíus Björnsson posted a photo of himself in costume on Instagram:
