Mikels said the script was brought to him by Pam Eddy and Jack Richesin: "It was three kind of naughty girls of the night getting together to take vengeance against somebody that did something to them. It evolved deeper and deeper, I did two or three re-writes on it, and finally the wife of Joseph Robertson did the final draft". Mikels said that Mary Martin and
Sissy Spacek came in for parts but the roles had already been cast: "I'm very pleased with everybody I had in it though. That turned out to be a forerunner of female power films".
Time Inc. contributor Ed White notes that the visuals for the action sequences near the end of the film are unusually dark. This part of the film was shot in a single night. The multiple submachine guns used by the actresses in this sequence were really a single weapon that was on temporarily loan to the director. == Reception ==
