Variety reports that The Black Hand will be about, ‘the origins of the mafia in America’, following Joe Petrosino, ‘an NYPD cop who goes after the ruthless gang in the early 190os. The thugs (with the calling card black hand) migrated from Italy to America, and kidnapped people to extort money from their families. They were loathed by law-abiding Italian families who were frightened, but nevertheless helped Petrosino behind the scenes.’
There’s no news on when we might get to see the movie, and it might be a while and DiCaprio is known for taking his time developing new films. Hopefully it won’t be too long though.
