Jay-Z and myself have been working tirelessly on the score for the upcoming #CLASSIC The Great Gatsby! It is too DOPE for words!— THE BULLITTS (@TheBullitts) December 30, 2012
It isn't known how extensive their involvement in crafting this score will be, since Craig Armstrong (The Incredible Hulk, Ray) is currently credited as the composer. Perhaps Jay-Z and Jeymes Samuel are working on new original songs for the soundtrack, although that has not been confirmed. Jay-Z and Kanye West's song "Church in the Wild" was featured in the first trailer that debuted back in May.
The Great Gatsby was released May 10th, 2013 and stars Lisa Adam, Frank Aldridge, Amitabh Bachchan, Steve Bisley, Richard Carter, Jason Clarke, Adelaide Clemens, Vince Colosimo. The film is directed by Baz Luhrmann.
