Actor, writer, and director Mike Cartel did his own stunts on the film, including being hit by a shotgun blast at close range while wearing a semi-protective vest; running and crashing through a full-size 'breakable' plate glass door; falling into a jukebox, over tables, and hard into walls from punches in a barroom fight; getting hit in the face by a heavy plastic 'stunt' bottle, and having three explosive squibs burst through a plywood background wall around his resting head.
This movie was made without permits.
The bar scenes were filmed on two separate locations: One location was a biker bar while the other location was a gay bar.
Retired 20th Century Fox SVP, Steve Escovido was the Assistant Cameraman on "Runaway Nightmare" (1982) during the endless weekend pick-up shot shoots in 1979.
