Sara Costa's range firing scenes were filmed on the Alhambra Police Department's shooting range in South El Monte, California, USA. All scenes shot involved real, live fire, using a Smith and Wesson .357 Magnum Model 19 revolver. The director wanted to show her firing an impressive score, so it was decided that the instructor, Patrick Alexander, would be off camera shooting the target which would then be inserted as if it was fired by Sara. In fact she was doing very well in her firearms self defense training, and the target that was shown in the final cut was actually shot by Sara Costa.
