The building at 55 Central Park West served as the home of Weaver's character and the setting of the Ghostbusters' climactic battle with Gozer. The art department added extra floors and embellishments using matte paintings, models, and digital effects to create the focal point of ghostly activity. During shooting of the final scene at the building, city officials allowed the closure of the adjacent streets during rush hour, affecting traffic across a large swath of the city. Gross remarked that, from the top of the building, they could see traffic queuing all the way to Brooklyn. At various points, a police officer drew his gun on a taxi driver who refused orders; in a similar incident, another officer pulled a driver through his limo window. When angry citizens asked Medjuck what was being filmed, he blamed Francis Ford Coppola filming "The Cotton Club". Aykroyd encountered science-fiction writer Isaac Asimov, a man he admired, who complained: "You guys are inconveniencing this building, it's just awful; I don't know how they got away with this!" Directly next to 55 Central Park West is the Holy Trinity Lutheran Church, which is stepped on by the Marshmallow Man.
