Which one of the five boroughs of New York City was not used in making the film "Serpico" with Al Pacino?

In the 1973 film "Serpico" when noting the five boroughs of New York City, the one which was not used in making the film "Serpico" with Al Pacino was Staten Island. The entire crime drama was filmed in New York City. A total of 104 different film locations were used. Four of the five boroughs of the city (Manhattan, Brooklyn, Queens, and The Bronx) appear (all except Staten Island). An apartment at 5-7 Minetta Street in Manhattan's Greenwich Village is used as Serpico's residence. Lewisohn Stadium, which was closed at the time of filming, was used for one scene.

In the 1973 hit film, Frank Serpico exposed widespread corruption of the New York City Police Department (NYPD) in the 1970s. In part what he did became famous because it kicked off the most influential study on police corruption in USA. Serpico was the first police officer in the history of the NYPD to step forward to report and subsequently testify openly about widespread, systemic corruption payoffs amounting to millions of dollars.

This film is one of Sidney Lumet's very best movies. "Serpico" is a highly entertaining movie about grim police corruption in New York City....It tells the tale of Frank's personal ordeal and exemplary career, while painting a vivid and credible portrait of the police force at all levels. This is a film that one would think the NYPD would never have allowed to be made on its city streets. But the NYPD did and the film was made!
