Miltos Yerolemou, who had a small bet memorable role as Arya Stark's sword trainer in the first season of HBO's "Game of Thrones," has joined the cast of "Star Wars: Episode VII" in an undisclosed role. Yerolemou has played numerous sword wielding characters throughout his career, so it is naturally being speculated that he will be called upon to use a lightsaber in the film. Though undisclosed, the role is said to be only a minor one.
