"There was no body because there was no murder. Repeat."A cult psychological thriller/horror film from 1973, directed by Brian De Palma. It was the first of his films in the thriller-horror vein, and featured Margot Kidder in an early starring role as well as De Palma regular character actor William Finley, who would go on the following year to star as the Phantom in his Cult Classic horror rock musical Phantom of the Paradise.The plot concerns a murder, witnessed by a reporter from a neighboring apartment window, committed by a young model who, it becomes apparent, was born one half of a set of conjoined twins. The film is, in part, a homage to the works of Alfred Hitchcock, and in particular borrows from and references Rear Window and Psycho.
— Dr. Emil Breton
This film contains examples of:
- Berserk Button: For Dominique, any man getting intimate with Danielle.
- Beware the Nice Ones: Danielle seems gentle and sweet, but suffers from trauma-induced Split Personality, one of her personalities a violent murderess.
- Carrying a Cake: Grace, finding the birthday cake during the investigation of Danielle's apartment, proudly bears it out to the detectives as proof of the existence of Danielle's twin, only trips and drops the cake onto the unimpressed detective's shoes.
- Chekhov's Gun: The psychiatric ward is mentioned by Grace's mother in the first half of the film. It doesn't make an appearance until toward the end of the film.
- Chekhov's Gunman: Dr. Breton is at first just a face in the audience of the opening sequence game show.
- Compelling Voice: Dr. Breton uses a deep, calm voice while hehypnotizes Grace.
- Discretion Shot: During Grace's hallucination nightmare, when Dr. Breton operates with the cleaver.
- Downer Ending: Or maybe Bittersweet Ending, if you assume that Dr. Breton deserved to die, and that Danielle/Dominique will be arrested for murder. Still, even at best, Grace remembers nothing of the murder she was investigating, courtesy of Dr. Breton's hypnosis...and the private detective is left watching the couch holding the body, somehow still thinking it'll lead to something big.
