Johnny Depp channels crime boss Whitey Bulger in this tense trailer for Black Mass

Warner Bros. has released a tension-filled U.K. trailer for crime thriller Black Mass starring Johnny Depp as the Boston crime boss. Scott Cooper (Out of the Furnace, Crazy Heart) directs Black Mass, which hits theaters on September 25th, 2015.

In Black Mass, Oscar nominee Johnny Depp plays Whitey Bulger and Joel Edgerton (The Great Gatsby, Zero Dark Thirty) plays FBI Agent John Connolly. The film also stars Benedict Cumberbatch (Twelve Years a Slave) as Whitey’s brother, Billy Bulger, who is a Massachusetts State Senator; Jesse Plemons (AMC’s Breaking Bad) as Whitey’s longtime partner in crime, Kevin Weeks; Sienna Miller (American Sniper) as Whitey’s lover, Catherine Greig; Dakota Johnson (Fifty Shades of Grey) as Lindsey Cyr, Whitey’s former girlfriend and mother of his only child; Rory Cochrane (Argo) as Steve Flemmi, another member of the Irish mob; Julianne Nicholson (August: Osage County) as John Connolly’s wife, Marianne; and Adam Scott (ABC’s Parks and Recreation) as FBI Agent Robert Fitzpatrick. Rounding out the main cast are David Harbour (End of Watch), Jeremy Strong (Zero Dark Thirty), Brad Carter (HBO’s True Detective), W. Earl Brown (Draft Day) and Corey Stoll (The Bourne Legacy).

Brian Oliver, Tyler Thompson, John Lesher, Patrick McCormick and Scott Cooper are producing the film, with Peter Mallouk, Lauren Selig, Brett Granstaff and Gary Granstaff serving as executive producers. The screenplay is adapted from the book Black Mass: The True Story of an Unholy Alliance Between the FBI and the Irish Mob, by Dick Lehr and Gerard O’Neill.

In 1970s South Boston, FBI Agent John Connolly (Edgerton) persuades Irish mobster James “Whitey” Bulger (Depp) to collaborate with the FBI and eliminate a common enemy: the Italian mob. The drama tells the true story of this unholy alliance, which spiraled out of control, allowing Whitey to evade law enforcement, consolidate power, and become one of the most ruthless and powerful gangsters in Boston history.
