Any fan of Game of Thrones will recognize Hafthor Julius “Thor” Bjornsson as Gregor Clegan (“the Mountain”). Bjornsson makes a living as a strongman, which led to an acting career. He is one of the few and the first to win three of the most prestigious strongman competitions in the same year. Bjornsson has a long history of winning competitions for his strength. Many people try to compare him to bodybuilders, but his build is less bulky and more strength focused. However, that didn’t stop him from looking the part in any of his acting jobs, including Game of Thrones.
