''Repulsion'' is a 1965 British psychological horror film directed by Creator/RomanPolanski, based on a scenario by Gérard Brach and Roman Polanski. It was Polanski's first English language film, and was filmed in Britain, as such being his second film made outside Poland. It is also the first film in his so-called "Apartment Trilogy" (followed by ''Film/RosemarysBaby'' and ''Film/TheTenant'').

Creator/CatherineDeneuve stars as Carol, a young Belgian manicurist who lives in London with her sister Helen. When Helen decides to go on a holiday to Italy with her married boyfriend, Carol is left home alone for a few days. [[MindScrew It doesn't turn out to be a very pleasant experience]].

!!This film provides examples of:

* AllMenArePerverts: Even seeming NiceGuy Colin has trouble respecting Carol's boundaries, and nearly ever other male in the film is lecherous, condescending, crude, unfaithful, or all of the above.
* CrankyLandlord: The landlord (who else?). In addition to being cranky, he's also a creep who tries to force himself on Carol.
* DoesNotLikeMen: Carol is either this, or just really, really afraid of them.
* DoggedNiceGuy: Really nastily subverted with Colin.
* EpicFail: Carol's attempt to hide the body and the murder weapon. For that matter, instead of simply ''locking'' the door, she nails a board in front with a candlestick. And it's ''[[SarcasmMode not noticeable at all]]'' that she overturned the sofa to hide her second body.
* {{Fingore}}
* GainaxEnding: [[spoiler: What the hell happened to Carol at the end? Is she dead, or just in some kind of a coma?]]
** [[spoiler: That would probably be from not eating much of anything for a straight week, ''including'' a rabbit. Starvation or dehydration, take your pick. The real question is why she was sleeping under the bed, among other things...]]
* GoMadFromTheIsolation: Carol, apparently much quicker than most people. Then again, she doesn't seem to have been all that sane to begin with...
* HairRaisingHare: The skinned rabbit that Helen plans to cook and that Carol leaves sitting out in the living room.
* LivingEmotionalCrutch: Helen doesn't seem particularly loving or supportive, but her presence keeps Carol (barely) functional, and it only takes about a week without Helen to cause Carol to become totally delusional and homicidal.
* MindScrew: The viewer is put in Carol's position of never knowing what's really happening and what she's hallucinating.
* MirrorScare: The first sign that Carol is more than just shy and high-strung.
* PietaPlagiarism: When she's knocked out due to whatever, one of the other tenants picks her up. Though it's more of a BridalCarry.
* ParalyzingFearOfSexuality: Taken to the extreme.
* QuieterThanSilence: Carol almost ''never'' speaks, so when she's alone in the house, this is natural. But special mention has to go to the [[spoiler: [[{{ImagineSpot}} Imagine Spot]]s where a man breaks into her room and assaults her.]] All we hear in those scenes is a clock ticking... and it's '''''[[NightmareFuel terrifying]]'''''.
* TheQuietOne: Carol fits this trope, to a T.
* RapeLeadsToInsanity: It's strongly implied, in the final shot, that [[spoiler: Carol's mental problems stem from being raped as a girl by a male relative or family friend]].
* SanitySlippage: The whole plot of the film.
