J.A. Steel told Femme Fatales magazine that she originally wrote the script with a more diverse set of characters, including a black male police captain called MacGregor and a female main character called Sanchez with martial arts skills. But when she started showing the script to development directors, they kept saying they liked it but everything was "too ethnic." One also told her to change Sanchez to a white woman with large breasts and give her fight scenes to the male characters. That's when Steel decided to finance the movie herself, though she did make Sanchez a white woman and changed her name to Jones.
