If you are a gambler or know the 'wiseguy' culture, the movie doesn't have to be explained, while if you aren't, you'll feel like you've stumbled upon the secret meeting place of the mafia and made privy to what is said, without anyone knowing you were there. The supporting cast is strong, led by James Woods and Don Rickles (excellent in his dramatic capacity), and the movie is generally well-acted. Sharon Stone plays the psychotic Ginger, a once-in-a-lifetime role in that it was the only time in my life I could bear to watch her on film. Rothstein's partner in crime is Nicky Santoro (Joe Pesci), who is far less convincing as a mobster than he would seem to like to believe. It was refreshing for a movie to finally show that not all gamblers are stupid, but instead one of those who takes advantage of the many who are. Rothstein is not a mob member, but a 'moneymaker' for them because he's the nation's best sports handicapper. As a lifelong gambler who has crossed paths with a few fringe types portrayed in the film, I'm well aware of the story, the culture, and the ambiance of the Tangiers, the fictional casino placed in the control of Sam 'Ace' Rothstein (Robert Deniro).
