It’s the type of exhaustive story that demands Martin Scorsese’s stylistic eye and William Monahan’s economical storytelling, but those two only paid spiritual homage to Bulger when they carved out 2006’s The Departed .
Black Mass is more The Departed than Goodfellas — Jack Nicholson’s mobster in the former actually was inspired by Bulger.
Based on the true story of James “Whitey” Bulger, the South Boston hood who inspired Jack Nicholson’s character in The Departed , it chronicles how Bulger (Johnny Depp) was able to stay out of prison because the FBI, led by Agent John Connolly (Joel Edgerton), uses him as an informant to help take down the Italian mafia out of North Boston.
Fictionalized depictions of murderous crime bosses have a little rope to play with; the distance from true-life means a filmmaker doesn’t have to be squirrelly about exploring the man inside the monster of a Michael Corleone or The Departed’s Frank Costello (reportedly inspired by Bulger).
