The golden age of heroes in Westeros has found at least one of its heroes in Naomi Watts. Martin’s prequel series—set thousands of years before the events of Game of Thrones, in the period of time where a fantastical golden age of magic and myth in the kingdoms of Westeros was forever transformed by the Long Night and the invasion of the White Walkers. Watts will play one of the untitled show’s primary roles, a currently-unnamed character who is “a charismatic socialite hiding a dark secret,” which, well, sounds very Game of Thrones-y.
