The trailer for Scott Cooper's (Out of the Furnace) Black Mass is here. Starring Johnny Depp, who is almost unrecognisable, as the infamous wanted US gangster, Whitey Bulger. The film tells the stranger-than-fiction story of how Bulger, the Bostonian head of the Irish mob, had illegal and strange underground dealings with childhood friend and FBI agent, John Connolly (played by Joel Edgerton), which spiralled out of control.

Dakota Johnson stars as Bulger's girlfriend and Benedict Cumberbatch plays Bill Bulger, a state senator and brother of Whitney. Kevin Bacon and Peter Sarsgaard also star alongside Depp in this real-life crime thriller. Take a look at the trailer below...
