The actress’ role is not officially confirmed, though Vanity Fair uncovered some clues that suggest she will play an actress in a troupe who portrays a version of Cersei (played by Lena Headey on the show).

Fellow “Game of Thrones” newcomer Richard E. Grant will play the actor portraying Cersei’s late husband, Robert Baratheon, according to the same report.

Davis joins other new “Game of Thrones” cast members including Max von Sydow, Ian McShane, and Freddie Stroma. Von Sydow will play the Three-Eyed Raven, while Stroma will play Dickon Tarly. McShane’s role is unknown.
