Casino Is Inspired By The Life Of Frank Lefty  Rosenthal\n\n Like De Niro's character, Frank Rosenthal was a professional sports gambler, a casino executive in Las Vegas, and an organized crime associate. Rosenthal learned sports betting as a youth, and by the mid-1950s, he was working with the Chicago Outfit.

In this traditional view, money is a gambler's primary motivation, and randomness in games allows the gambler to hope that the gains will overcome the losses.
