Guy Pearce Playing Johnny Depp's Brother in 'Black Mass'!

Guy Pearce is set to star alongside Johnny Depp as his brother in the upcoming film Black Moss, according to Variety.

The film will see Johnny take on the role of Boston mob boss Whitey Bulger, who was also an FBI informant who eliminated criminal competition with his status. He eventually went on the lam and lived with his girlfriend in a Santa Monica apartment building after he was tipped off that the FBI was on to him. He was caught in 2011.
