Deadline reports that Edgerton has joined the cast of Black Mass as FBI agent and childhood pal of Bulger, John Connolly.  Connolly was tasked with taking down the Italian mob and cooperated with Bulger, who acted as an FBI informant with the dual intention of getting the Feds to eliminate his own underworld competition.  Connolly himself was eventually convicted of racketeering and obstruction of justice for aiding Bulger, along with second-degree murder charges stemming from leaked information to the mobsters.

Deadline also reports that Pine, Seyfried and Ejiofor will join Z for Zacharia.  Here's the press release:
