Director Jim Sheridan, who helmed rapper 50 Cent's "Get Rich or Die Tryin'" film in 2005, is tackling a new project about the disappearance of mobster Whitey Bulger.

Sheridan has written a script with Nye Heron based on the "Black Mass: The True Story of an Unholy Alliance Between the FBI and the Irish Mob" tome by Boston Globe reporters Dick Lehr and Gerard O'Neill.

The book chronicles the life of Bulger from being a powerful mob enforcer and being an FBI informant to his mysterious disappearance.

The director told Daily Variety, "This is a story of a corrupt system and about how an angry guy became the second most wanted man after Bin Landen."

The film will be produced by Michael Cerenzie and Christine Peters of CP Productions and Brian Oliver of Arthaus Pictures.
