Charlie Hunnam has joined the cast of ‘A Million Little Pieces’.

The Sons of Anarchy actor will work with director Sam Taylor-Johnson on the big screen adaptation of James Frey’s book according to The Hollywood Reporter. The actor previously turned down the role of Christian Grey in the ‘Fifty Shades of Grey’ franchise which is also directed by Sam.

Charlie will play the brother of the lead character, 23-year-old alcohol and drug abuser James, a role that has already been filled by Sam’s husband Aaron Taylor-Johnson.

Billy Bob Thornton has also joined the cast as a mafia boss James meets in rehab, who becomes a great support in his recovery, while actress Carla Juri has signed up to play the female lead, a crack and heroin addict who falls in love with James.
