When the first trailer for director Baz Luhrmann’s ambitious adaptation of the classic novel The Great Gatsby debuted online, many were jarred by the juxtaposition of Jay-Z and Kanye West’s “No Church in the Wild” against the film’s period setting.  The decision to use that song in the trailer wasn’t a complete shock, as Luhrmann has shown a propensity for populating his period films with modern music.  He had no problem mixing Shakespeare with Radiohead in Romeo + Juliet and 1900s France with Madonna in Moulin Rouge!.  Now, though, it appears that Luhrmann isn’t just repurposing existing songs for The Great Gatsby, but is having Jay-Z himself provide an original score for the film.  Hit the jump for more details.
