Evil Doctor Bill Cortner is a rule-flouting maverick who has been experimenting with the transplanting of human limbs and organs, and even repairing and reconnecting of nervous system tissue — much to the displeasure of his traditionalist surgeon father. But Cortner gets a chance to prove he's not been wasting his time when his fiancee Jan is decapitated in a car accident. Cortner quickly uses 'neck-pan juice' to keep her head alive while he searches for an attractive body to reattach it to. Jan, however, has her own agenda...For the Mystery Science Theater 3000 version, please go to the episode recap page.
The Brain That Wouldn't Die contains examples of:
A God Am I: While not stated, Cortner's father tells him that he shouldn't be trying to play God.
All Men Are Perverts: At least, according to Doris, the man-hating fashion model Cortner encounters near the end of the film. In her defense, she was hideously scarred after a man attacked her.
Applied Phlebotinum: That strange serum Cortner uses to expedite organ grafting and preservation.
Artistic License - Biology: The neck juice may replace the need to breathe, but one still needs lungs to be able to speak. Also, getting your head lopped off and reanimated probably won't make you telepathic.
Cat Fight: The two strippers argue over who gets Cortner, at which point he walks out (he can't use either of their bodies, because either one would be a witness to the others disappearance). When the first one complains about the second chasing him off, her retort leads to a wrestling match.
Bonus points for the film actually showing a picture of two cats during the fight!
Chick Magnet: Cortner attracts women like flies... which isn't a good thing, because as he points out, "I can't be the last man seen with a woman before she's killed!"
Death by Irony: The closet monster rips off Kurt's good arm. So now he can't do things like open doors to escape.
Impairment Shot: Cortner spikes Doris' drink to sedate her for head-removal. The camera switches to her POV as she staggers around before collapsing.
Crow:[As Dr. Cortner, warbblely] My mother gave me that glass, it was a family heirloom! Wubwubwubwubwubwubwub...!
Jumping Off the Slippery Slope: Cortner starts the film abrasive and arrogant, but his stated motivation of saving lives is admirable, and he is trying to restore his girlfriend Jan to a whole body. However, once he starts trawling around seeking a girl to kill for her body, all bets are off.
He had been stealing parts from the morgue even before Jan's "death". As Mike says, "That's mildly unethical."
Not to mention making the brainless monster in the closet and being the cause of Kurt's gimpy arm.
Psychic Powers: Jan takes "differently-abled" to a new level - being just a head gives her psychic powers.
Science Is Bad: Cortner's experiments for transplanting human limbs, organs etc. Long before Jumping Off the Slippery Slope, Cortner saves a man's life during emergency surgery using his "radical" techniques... and is promptly chewed out by another doctor (his own father, at that).
Sexophone: "The Web", which plays every time Cortner goes trawling for bodies.
Title Confusion: The film's closing title card presents the title as "The Head That Wouldn't Die", the original title. They changed the main title (and the poster) because sci-fi films with the word "brain" in the title were all the rage.
Too Dumb to Live: Sure, Cortner, walk up to the closet when you hear the odd knocking. The closet your assistant's blood trail starts at.
Cortner looks Doris dead in the eye and tells her frankly that he's going to cut her face off and discard her body. She just laughs.
Truth in Television: Kurt's death throes. While it is goofy at first glance, in reality many of the things he does during those few minutes (stumbling around, repeating movements and actions he did earlier, convulsing even while he's able to walk upright) have been known to be things people may actually do when they are in a deep state of hemorrhagic shock due to a catastrophic injury, especially if they don't die instantly.
Ungrateful Bastard: Jan. Cortner brought her back to life. He's going to give her the body of a model, and she won't even have to lift a (proverbial) finger! All she can do is complain, complain, complain! "Oh, this is unnatural! Oooohhhh, I'm a thing of horror! Why won't you let me diiieee!". Gah!
On the other hand, her fiancÚ is out to brutally kill a woman to give her a new body, and she just realized what he did to get to the point he could preserve her life. And if he succeeds at giving her a new body, do you think he'll ever let her leave? If it's a choice between living with that and dying, one can't blame her for picking the latter route.
Let's not forget that Jan Came Back Wrong and may be insane in the first place.
Oh, perhaps, she prefers death and didn't want to come back.
