Johnny Depp will star as notorious gangster Whitey Bulger in "Black Mass," an upcoming film that "Rain Man" director Barry Levinson will direct, reports. The film chronicles a gangster who was on the FBI's Most Wanted List for more than a decade and was also an FBI informant. Bulger also served as the basis for Jack Nicholson's character in "The Departed." Ben Affleck has his own project in the works with Matt Damon likely to play Bulger, but Depp's film will enter production first.
