After winning an Academy Award for Best Adapted Screenplay for The Departed in 2007, William Monahan was hired to work on two film projects: an adaptation of the Hong Kong film Confession of Pain and an original rock and roll film, The Long Play. Monahan will executive produce and write the adaptation for Confession of Pain. The adaptation of Confession of Pain will be produced by Leonardo DiCaprio's production company Appian Way for Warner Bros. Pictures.[30] Monahan's other assignment is to rewrite a screenplay about the history of the rock music business called The Long Play. The Long Play is the creation of Mick Jagger, the lead singer of The Rolling Stones, and was nurtured at Jagger's production company Jagged Films. Martin Scorsese became involved while the film project was at Disney but recently negotiated a turnaround deal to bring the The Long Play to Paramount.[31]
