Final part of the Scorsese underworld crime trilogy that began with “Mean Streets” and continued in “GoodFellas.” Casino boss Sam “Ace” Rothstein (De Niro), his ex-hustler wife Ginger (Stone), and his loose-cannon enforcer pal Nicky (Pesci) are the principals in this lengthy, fictionalized account of how the mob lost Las Vegas in a haze of drugs, sex, coincidence, and betrayal.
