In The Godfather, Luca Brasi was played by ex-wrestler and ex-bodyguard for the Colombos, Lenny Montana. The paparazzi in the wedding scene was also part of the Italian American Civil Rights League which was connected to the Colombos.

In A Bronx Tale, Eddie Mush was played by himself. He may not be a Mob guy per se but he was a neighbourhood guy and a degenerate gambler.
