Body Heat is a 1981 neo-noir erotic thriller. It was directed by Lawrence Kasdan and stars William Hurt and Kathleen Turner.Ned Racine is an incompetent and sleazy Florida lawyer who begins an affair with Matty, a seductive woman married to a wealthy man. Fearful that her husband would find out about them and leave her penniless, Matty convinces Ned to kill her husband so they can be together.
This film provides examples of:
- Ambiguous Ending: The fact that Ned had gotten concrete confirmation of his theory—and his cop friend indicated that he needed proof to go looking for "Mary Ann". Also, we are left wondering from Matty's/Mary Ann's expression if she partly regrets all she's done.
- Ambulance Chaser: Even before being seduced into a murder plot, it's clear that William Hurt's character is a particularly disreputable low-rent lawyer.
- The Bad Guy Wins: The manipulative villainess has effortlessly manipulated the dumb lawyer throughout the film and convinced him to murder her rich husband. She fakes her own death and leaves the country with her late husband's money, while the lawyer is left to take the rap for two homicides.
- Black Widow: Matty/Mary Ann. Seduces her lover into killing her husband, then leaves him to take the rap for this and yet another murder. And in a state like Florida, he could very well be on his way to death row for that.
- Bookends: The film begins and ends with characters commenting on the heat.
- Cassandra Truth: Ned figures out that Matty/Mary Ann is alive. Unfortunately, given his involvement in her husband's murder as well as the numerous other crimes he's committed, no one believes him.
- Corrupt Corporate Executive: Matty's husband is implied to be this. Though he himself comes across as a somewhat likeable fellow, the implication grows throughout the film that his group of businessmen are involved in some pretty crooked stuff—to the point that Ned's D.A. friend notes it's almost a good thing the man's dead.
- Creepy Souvenir: The sunglasses Matty is wearing at the end are set in the glasses frame of her late husband.
- Empathic Environment/Heat Wave: The film takes place during an especially hot Florida summer.
- Faking the Dead: Matty/Mary Ann at the end.
- Femme Fatale: Kathleen Turner, in spades.
- Film Noir: Solidified the genre's return.
- Hotter and Sexier: Specifically, to Double Indemnity and (less directly) The Postman Always Rings Twice, actually showing the sexuality those earlier films could only hint at. More generally, the film is one for Film Noir in general—and in being so, it helped set the standard for the Film Noir-Erotic Film trend of The '80s and The '90s.
- Primal Scene: Edmund's niece walks in on Matty and Ned, but she doesn't get a clear look at Ned's face. After Edmund's murder, it comes back to haunt them when little girl tells the cops what she saw, though she can't remember what the man looked like. As it so happens, Ned is at the police station on other business when this happens and one of the cops mentions it to him. Knowing that they're suspicious of him and Matty and that if he tries to avoid being seen by the little girl it will confirm that he has something to hide, he calls their bluff by walking right past the girl and her mother.
- Tropical Epilogue: Kathleen Turner's character ends this way, whatever her name may be.
- The Vamp: Mary Ann Simpson is explicitly labeled "The Vamp" in her high school yearbook. She's Kathleen Turner's character, which we've been lead to believe is Matty Tyler Walker, and is playing Ned Racine, the real Matty Tyler, and her husband for all they are worth.
- Very Loosely Based on a True Story: Like Double Indemnity (which it's a vague remake of), it's based on the Snyder-Gray murder.
