This was the very last film distributed by Allied Artists Corporation (early in its life, Allied Artists was known as Monogram Pictures, and was responsible for all the Bowery Boys/East Side Kids films (under the monikers; Little Tough Guys/Dead End Kids, their films were released by Universal). Citing extreme financial difficulties, Allied Artists filed for Chapter 11 in late 1978, and the following year, their entire catalogue (including the Monogram films) was purchased by Lorimar/Telepictures Corporation (itself subsequently purchased by Time Warner, Inc. a decade later). Some TV prints of the Bowery Boys features, the WB 'shield' logo precedes the opening credits).
The film's screenplay was co-written by Jerry Harvey, with Douglas Venturelli. Mr Harvey was the driving force for the legendary early (L.A. only) film cable channel (1974-1988), the Z Channel, which aired finds - rare, uncut, all at a time before VCR's (much less video stores and now digital). Z Channel's place in film history is documented in the film, Z Channel: A Magnificent Obsession (2004), by Xan Cassavetes, daughter of noted director, John Cassavetes, and actress Gena Rowlands.
