This compelling film, combining both art film and documentary techniques, evolved out of the landmark Science magazine article Milgram wrote in 1970 that essentially established the field of urban psychology. In the film, Milgram introduces the concepts of urban overload and selective attention and delves into the research of social psychologists John Darley and Bibb Latane, who studied New York City in the aftermath of the shocking murder of Kitty Genovese.
