This was one of two features produced by an independent company in Texas and meant for release as a double feature. The other feature was The Killer Shrews (1959). Unlike many such features produced in the South, these films received national distribution.
Gordon McLendon, who owned a number of radio stations and theaters in Texas, was the uncredited executive producer and financier of this film. Some members of the McLendon family were given roles in this film.
The voice you hear on the other end of the phone, when Chase eavesdrops on a phone call to the police department, is that of Ken Curtis, who served as producer on this film. He is more famous for having played scruffy deputy Festus Hagen on Gunsmoke (1955).
