The movie directed by Out of the Furnace filmmaker Scott Cooper tells the story of Boston crime king-pin turned fugitive Whitey Bulger who was the leader of the notorious Winter Hill King. He topped the FBI's list of most wanted criminals before disappearing without trace for over a decade. The Great Gatsby actor Joel Edgerton is slated to star opposite Depp as crooked FBI agent John Connolly, who was tasked with tracking down Bulger but aided in his disappearance, reports Deadline.com.

Johnson will play Linsey Cyr, the girlfriend of Whitey and mother to his six-year-old Douglas who dies tragically.

The excellent Guy Pearce has been cast as Bill Bulger, brother of the infamous mobster who was president of the Massachusetts Senate.

Bulger was eventually arrested in California in 2011 and is currently serving time in a Massachusetts state prison for second-degree murder.

Ben Affleck and Matt Damon have been circling a Whitey Bulger movie for a while now, with Boardwalk Empire creator Terence Winter apparently penning the script. The Boston Herald say the movie is still on track, despite Depp's movie, which is based on Dick Lehr and Gerald O'Neill's 2001 New York Times best-seller Black Mass: The True Story of An Unholy Alliance Between the FBI and the Irish Mob.

Black Mass will hit theaters in October 2015.
