Johnny Depp was almost unrecognizable when spotted on the set of his new movie "Black Mass". He was spotted in Boston, Massachusetts wearing a bald cap with thin blond hair to portray Whitey Bulger in the true-story movie, AceShowbiz said.

Bulger was an FBI informant in taking down a Mafia family who invaded his turf. However, he was later outed as a criminal himself and went into hiding when the Feds closed in on their targets. He became a fugitive for years before being arrested in 2011.

Joel Edgerton will play FBI agent John Connolly, Bulger's childhood friend. Connolly himself ends up in prison for tipping Bulger about the Feds' plan. Guy Pearce will play Bulger's brother, Bill, who was president of the Massachusetts Senate and a big power broker in town.
