Tyler Bates has revealed in recent interviews with Scorenotes and Billboard that he has written music for the black comedy Killer Joe. The film is directed by William Friedkin (The Exorcist, The French Connection) and stars Matthew McConaughey, Emile Hirsch, Thomas Haden Church, Gina Gershon and Juno Temple. Tracy Letts (Big) wrote the screenplay based on his own play. The movie centers on a family who hires a police detective-turned-hitman to kill their mother for her life insurance policy. Nicolas Chartier (The Hurt Locker) and Scott Einbinder (The Forsaken) are producing. No word yet on if any of the score by CC Adcock (who was originally announced as the composer of the film) remains in the movie. Killer Joe is set to premiere at the Venice Film Festival in a couple of weeks and will also be shown at the Toronto Film Festival in September. A release date for the comedy has yet to be announced.

Bates’ music can currently be heard in theaters in the remake of Conan the Barbarian. As previously reported, he also has Emilio Estevez’s drama The Way coming up in October. The composer is currently working on the score for the fifth season of Showtime’s hit show Californication starring David Duchovny, which is set to debut in early 2012. Bates also already finished the score for the sci-fi horror film The Darkest Hour directed by Chris Gorak and starring Emile Hirsch, Rachael Taylor, Olivia Thirlby and Max Minghella. The release date of the film has been pushed back to December 25, 2011 since our last update. For updates on the project, visit the official movie website and check out the trailer below.
