Our latest guests on Soundtracking are husband and wife duo Aaron and Sam Taylor-Johnson, who have joined forces on a number of levels to bring us A Million Little Pieces.

An adaptation of James Frey's book of the same name, it's based on the author's experiences in rehab as he attempted to recover from alcohol and drug addiction. Despite the well-documented controversies surrounding the veracity of some of James's account, there's no denying it's power as a study of what it's like to hit rock bottom.

Sam and Aaron wrote the script together, before Sam got behind the camera and Aaron in front of it to take the lead role. They also worked as producers on the film.  The score, meanwhile, is provided by Atticus Ross - a frequent collaborator with Trent Reznor.
