MASSIVE SPOILER FOR DRESSED TO KILL
(In case anyone wants to watch it)
From Wiki
“Elliott is arrested and placed in an insane asylum. Dr. Levy explains later to Liz that Elliott wanted to be a woman, but his male side would not allow him to go through with the operation. Whenever a woman sexually aroused Elliott, Bobbi, representing the unstable, female side of the doctor's personality, became threatened to the point that it finally became murderous. When Dr. Levy realized this through his last conversation with Elliott, he called the police on the spot, who then, with his help, did their duty.“
That’s just a mess on so many fronts. (Can you tell I’m not a DePalma fan?)
