 The character of Ray Luca (Anthony Denison) is based upon Chicago  mobster Tony "The Ant" Spilotro. Spilotro also inspired Joe Pescis  character of Nicky Santoro in "Casino". By the same token, Andrew  "Dice" Clays character of Max Goldman and Robert DeNiros character  of Sam "Ace" Rothstien in "Casino" are both based upon Spilotros  partner, Frank "Lefty" Rosenthal.
