Johnny Depp plays south Boston wiseguy James “Whitey” Bulger, whose heyday was the 70s and 80s. With his bald head and weird blue eyes, Depp’s Bulger is a fully paid up sociopath with a groany-deep voice. His brother, Massachusetts State Senator Billy Bulger, is played with a cat-that-got-the-cream smirk by Benedict Cumberbatch: Billy effectively manages what could only be described as the political wing of Whitey’s organisation. The Bulger boys grew up in the same Irish-American community as ambitious FBI agent John Connolly, played by Joel Edgerton, who gives Whitey virtual immunity from prosecution, in return for supposedly valuable “intel” on the Italian mafiosi in the North. Contains strong bloody violence, strong language.
