The drive-in location seen in this film had closed down when the movie was filmed in 1985. The drive-in has now been demolished and no longer exists.
Two of the films playing at the drive-in in the film are The Man from Hong Kong (1975) and Turkey Shoot (1982), also directed by Brian Trenchard-Smith.
According to the documentary Not Quite Hollywood: The Wild, Untold Story of Ozploitation! (2008), this movie is Quentin Tarantino's favorite Brian Trenchard-Smith flick. Tarantino is fan of Trenchard-Smith's work.
Apparently, to get the part in this picture, actor Ned Manning allegedly told director Brian Trenchard-Smith he was twenty-four years old, but in reality, at the time of casting, was thirty-six years of age.
The movie poster seen early in the film was for the fictitious film "Rambo 8: Rambo takes Russia".
