Surely to be controversial, this brief video from Bloodletters & Badmen attempts to correct many of the historical inaccuracies. Hollywood, perhaps more than any other has misrepresented a lot of the people and events surrounding the Castellammarese War between the two Mafia factions of Joe "the Boss" Masseria and Salvatore Maranzano. I hope this video will help in correcting some of there mistakes.
