Presented below is 1979s Over the Edge, a film favorite of mine.
Directed by Jonathan Kaplan (Night Call Nurses, The Student Teachers, Truck Turner, The Accused, Bad Girls, etc.) the film was completed in 1979 but was never widely released into theaters. The studio was concerned that the film's subject manner was too controversial and would incite violence among teen viewers, ala The Warriors, and subsequently shelved the film for two years before finally selling it to HBO, which is where I first came upon it. The response was positive and special screenings then took place.
