5. Edmure Tully (Tobias Menzies)
Another new-comer to Season 3, Tobias Menzies face is probably more recognizable than his name. In Game of Thrones he plays Cat Stark's obnoxious and incompetent brother, Edmure Tully. We first see Tully in an agonizingly awkward scene in which he attempts (and fails) to light his father's funeral barge as it drifts further and further away down the river. Menzies has remained largely in the television sector throughout his career but may be most well known for his role as Judi Dench's right-hand man in Casino Royale. He played the character 'Villiers' in the 2006 reincarnation of Ian Fleming's spy series but, for whatever reason, failed to maintain the role in the following two Bond outings. Other notable roles include Rome, as Marcus Brutus (alongside Ciaran Hinds) and the BBC's The Shadow Line with Christopher Eccleston. Appearances in Spooks, Any Human Heart, Doctor Who, The Deep, Black Mirror, The Thick Of It, Law & Order: UK and Casualty have also laid foundations for a filmography that any actor could be pleased with.
