If you’ve ever watched GoT and thought “huh, the Mountain looks a little different,” it’s not just because the show hasn’t been on for a while. Gregor The Mountain Clegane has been played by three different actors. Conan Stevens was on board for season one, but he was replaced by Ian Whyte in the second season. The character was played by Hafþór Júlíus Björnsson for the fourth, fifth and sixth seasons.
