Irish director Jim Sheridan has started working on a film about Boston mobster and FBI informant Whitey Bulger.
The 'In The Name Of The Father' director's latest project is based on the book Black Mass: The True Story Of An Unholy Alliance Between The FBI And The Irish Mob, which was penned by Boston Globe journalists Dick Lehr and Gerard O'Neill.
Black Mass told the story of Bulger's rise as he took over the Winter Hill Gang, which organised gun trafficking for the IRA and drug running.
It also revealed Bulger's childhood friendship with FBI agent John Connolly, who used him as an informant until he disappeared controversially in 1995.
Miramax originally acquired the rights for the book with the intention of using Matt Damon and Ben Affleck in the film. However, their rights have now expired and Sheridan is penning his own script for the movie.
