Hugh Dancy has joined the cast of Fifty Shades Darker. The Hollywood Reporter confirms, the 40-year-old actor has signed up to play bondage-loving billionaire Christian Grey's psychiatrist Dr John Flynn in the sequel to Fifty Shades of Grey. Jamie Dornan's Christian starts seeing the psychiatrist after his former lover, who introduced him to the world of S&M at the age of 15, returns and affects his relationship with Anastasia Steele, who is played by actress Dakota Johnson. The English-born therapist moved to Seattle after marrying an American woman so Hugh will be able to keep his own accent for the movie.
