In the movie Casino(1995)Robert DeNiro plays Ace Rothstein, a fantastic bookie who is chosen to run the Tangiers hotel and casino. Along the way, he marries a drug-addicted con-artist trophy wife (Sharon Stone) and struggles with his friendship with loose-cannon Nicky Santoro (Joe Pesci). Rothstein is a complicated figure in that he is not a heavy, yet he wields a lot of power due to the respect he has gained from his mob bosses back home.
