We've reported on this before, and probably will again.
Philip Noyce, out doing the publicity rounds for his latest film Salt is also talking about his adaptation of Tim Winton's novel Dirt Music. It appears that Russell Crowe is definitely on board as the male lead - replacing a role originally slated for Heath Ledger - and, according to Noyce, has been producing music for the film for the past few years. And, no, I won't comment on that last piece of news.
The Internet Movie DataBase has a listing for the film but all details about cast and crew are behind their paywall.
