This lyrical, slice-of-life documentary (by Helen Levitt, James Agee and Janice Loeb) about East Harlem is one of several outstanding children's documentaries ("The Quiet One" and "Louisiana Story," among others) produced immediately after World War II. The filmmakers captured the energy-filled streets as part theater, part battleground and part playground. In their everyday lives and actions, people project an image of human existence against the turmoil of the street.
