Kit Harington in Game of Thrones
None of the actors who auditioned on Game of Thrones could have predicted the success of the show, but Kit Harington was by far under the most pressure. Harington's character, Jon Snow, evolved into the closest approximation to the show's central protagonist—and Harington had a hard time handling the stress.
"It wasn't a very good time in my life," Harington told Variety. "I felt I had to feel that I was the most fortunate person in the world, when actually, I felt very vulnerable."
