The original ending of Fatal Attraction actually had Alex commit suicide. But that didn’t “test” well. Alex had terrified the audiences and they wanted her punished for it. A tortured and self-destructive Alex was too upsetting. She had to be blown away. So, we went back and shot the now famous bathroom scene. A knife was put into Alex’s hand, making her a dangerous psychopath. When the wife shot her in self-defense, the audience was given catharsis through bloodshed — Alex’s blood. And everyone felt safe again. The ending worked. It was thrilling and the movie was a big hit. But it sent a misleading message about the reality of mental illness.
