I have just published an article on the 1970 collective film STREET SCENES 1970, which was produced and edited by Martin Scorsese while he was a part-time professor at NYU. STREET SCENES has been a largely forgotten piece of Scorsese's career, and this is the first full-length piece on the film and its production and reception. The article is in the latest issue of FILM HISTORY. It is available for download but only if you have a subscription. The journal is also found in most libraries.
