This film really struck a chord with the gay community and has remained a favorite of a small cadre of fans. Craig Russell has a very interesting history. He worked as an assistant to Mae West and went on to have a nice career as a performer, doing this film and a sequel to it - Too Outrageous (1987), as well as club dates and guest appearances on television. Look for Helen Shaver in a small part as well.
The fans of this film know it well, though the general public isn't really aware of it. It's available on DVD. A promotional trailer for the DVD is above, uploaded to YouTube by DigitalClassics.
Obscurity factor: 6 (known to fans, otherwise largely unknown, on DVD)
