Adapted by Waldo Salt and Norman Wexler from Peter Maas’s book, and shot on location with a gritty emphasis on documentary-style realism, Serpico presents a city in decay both literally and morally, as everybody is in on the take, and the cops and criminals are almost interchangeable. Released in late 1973, after months of revelations of Presidential malfeasance in the breaking Watergate scandal, Serpico’s true story of bureaucratic depravity touched a cultural nerve, and the film became a hit with both critics and audiences, particularly for Pacino’s complex performance as the honest, long-haired whistleblower. One year after his star-making triumph in The Godfather, Pacino was nominated for an Oscar again, and lost again; Lumet and Pacino would reunite two years later for another true New York story, Dog Day Afternoon.
