David Harbour "Bribed" Into "Black Mass"

Tony-nominated actor David Harbour ("The Equalizer ," "A Walk Among The Tombstones")  has joined the crime biopic "Black Mass" says Deadline.

The story follows South Boston criminal James "Whitey" Bulger (Johnny Depp) who was betrayed by the FBI after he became an informant to bring down a rival crime family. Bulger was captured in June 2011 in Santa Monica following a 16-year manhunt.

In the 1970s, the pair joined forces with Bulger turning in his rivals to consolidate his power while Connolly scored the professional benefits of being the man who helped dismantle the mob. Eventually, Connolly was convicted of racketeering, obstruction of justice, and second-degree murder. Australian actor Joel Edgerton was attached to play Connolly at first. Now, Hardy isn't involved and Edgerton has come back to the role.
