Fifteen years ago this year, Game of Thrones premiered and changed the television landscape while turning its talented cast into overnight sensations. To this day, stars like Kit Harington, Peter Dinklage, and Emilia Clarke remain closely associated with the world of Westeros, even though their filmographies go well beyond the HBO hit. Oftentimes, it's fun to go back and revisit actors' other roles, watching them inhabit other characters; in the case of Game of Thrones, this practice allows viewers to check out their favorite performers in roles that might have happier endings or less twisted storylines.
