A&E made this biography of mobster Frank Nitti's life. It follows him from his arrival in the United States until his death by his own hand in 1943.
Nitti and his family lived in the navy yard section of Brooklyn after emigrating. Italians were a minority in that neighborhood, so Nitti had to be tough to deal with being attacked by the Irish mobs that frequented his neighborhood at the time. His stepfather was chronically unemployed, so Nitti left school to support the family. This delayed him leaving home until age 24, when his stepfather finally got a steady job.
He went to Chicago, and when Al Capone climbed to the top of the syndicate, Nitti went with him. He took over Capone's empire when Capone was sent to prison on tax evasion.
Nitti had a reputation of being an executive type - organization and planning were his hallmarks, not the actual acts of violence that his business required. So the 1987 film "The Untouchables" and The Untouchables TV show have him characterized all wrong, probably because the real Frank Nitti was not that interesting. That doesn't mean he didn't order and endorse the violent acts that were committed.
After the first ten minutes this documentary gets going, but for the first ten there are some rather cheesy overdone graphics and reenactments that subtract just a little bit from my overall score. But the actual information conveyed is correct and detailed.
