In The Street/Helen Levitt

WIKI: "In the Street is a short 1948 silent film shot in New York City directed and edited by American photographer Helen Levitt, assisted by novelist and critic James Agee and fellow photographer Janice Loeb. In the Street was shot with small 18mm hidden cameras and documents the grim realities of Harlem street-life, especially that of its children at play. It can be seen as a continuation of Levitt's exploration of children's street culture prevalent in her photography, but also explores the mundane life led by their working class parents."
