Who doesn't love the Mother of Dragons? The Game of Thrones star might just be the show's biggest breakout performer. Her willingness to take on risque scenes has certainly made her a fanboy favorite, but she has also proven to be a tremendous actress capable of playing a variety of roles. She'll be appearing in the upcoming film Dom Hemingway, starring Jude Law, and will star alongside James Franco in the film Garden of Last Days.
