James Norton is to star in a new Guy Ritchie film about the British aristocracy called Wife And Dog. The Happy Valley star joined previously announced cast members Remains of the Day actor Anthony Hopkins, The Imitation Game actor Benedict Cumberbatch and Gone Gi rl actor Rosamund Pike.

James Norton has joined the all-star cast for Wife & Dog, the new film from director Guy Ritchie. The star, known for his roles in Happy Valley and The Trial of Christine Keeler, is the latest big name to join the project, which sees the filmmaker "return to the colourful, back-stabbing world of the British aristocracy."

A trio of U.K. stars have joined Guy Richie’s “Wife & Dog,” rounding out the cast of the director’s next adventure into the colourful and backstabbing world of the British upper classes (which he recently explored in "The Gentleman" film and TV series).
