I have seen this film on several occasions ( though not lately), have spoken to its author , and have known several of its cast members, the most notable of which would be Lawrence Cook and Paula Kelly. For a time the film was withdrawn from circulation, though it was briefly brought back in a limited release in the late 1980s. It was made on a shoestring budget. The subject matter was so controversial that the then Mayor of Chicago would not allow it to be filmed in the city, which is where Greenlee had sought to film it. Gary, Indiana had to be the stage, instead. Despite the obvious budget ( and therefore technical) limitations--not to mention the dearth of then well known names--the film is highly effective. Many a movie patron who sat through it went home feeling somewhat--perhaps considerably--less secure about himself and the world around him. I loved the film.
