Notorious Boston gangster Whitey Bulger came to Deadline’s big awards-season event, The Contenders Presented By Deadline, which took place last month at the DGA Theatre before a sold-out crowd of AMPAS and key guild members. OK, Bulger didn’t appear in person. He’s in prison. But some very key filmmakers who have brought his chilling story to life in the contenders event sold outWarner Bros’ Black Mass did get a chance to sit down with me and discuss the making of this acclaimed drama, which director Scott Cooper says is less a traditional gangster film and more a character study of a sociopathic personality.

Cooper also talks about the tough challenge of doing something in a genre that already contains many of his favorite movies such as The Godfather and Goodfellas to name just two. There was also a responsibility to the victims’ families as the film actually shot in locations in Boston where all of this takes place.

In addition to Cooper — who also discusses the casting of Johnny Depp — producer John Lesher (an Oscar winner for Birdman), actor Rory Cochrane, film editor David Rosenbloom and composer Tom Holkenborg participated. Lesher answers my question about Bulger actually having seen the film in prison, Cochrane talks about meeting the real people portrayed in the movie and the moment he first saw Depp in full makeup as Bulger, Rosenbloom discusses his working relationship with Cooper, and Holkenborg talks about the subtlety of the score.
