If your life's aspiration is to be a casino high roller, then you really need to rethink everything about your purpose. But if you have done well from a life of crime, or have a super-rich and senile dad, or won the lottery, then knock yourself out and call up the casino for a private jet to take you across the street. You'll need to be able to bet bigger than anyone and throw good money after bad. Your bank manager will hate you, but the casino will shower you in love with free incentives.
No movie catches those early years of the building of las Vegas better than Scorsese's Casino. Set in a fictional Tangiers Casino, it tells the story of the casino's manager, Lefty Rosenthal. Trying to run an upright establishment, ut with the mafia wanting their cut, and a crazy mobster constantly undermining him, Rosenthal has to walk a fine line. When things do go sideways, the movie descends into the dark and grim universe of the mafia's underbelly. Robert De Nero absolutely nails the part.
