Rosemary's Baby: The Horror of Being Not Believed

There is a devil in Rosemary’s Baby, and a coven of Satanists, and eventually a cradle draped in black with an upside-down crucifix hanging over it. None of that is what the film is about. What the film is about is a young woman telling the people around her that something is wrong, over and over, in a rising register of politeness and panic, and being smiled at and medicated and sent home. Roman Polanski’s 1968 film — his first made in America, adapted with almost fanatical fidelity from Ira Levin’s bestseller — is the definitive horror film about gaslighting, made two decades before the word entered common use. The Satanism is the alibi. The horror is the not-being-believed.

Polanski shot it as a piece of sun-filled New York realism, all cheerful yellows and browns and Manhattan light, which is the first of its quiet cruelties. Rosemary and Guy Woodhouse move into the Bramford, a grand old apartment building modelled on the Dakota, and their new life looks like an advertisement. The dread accumulates so gradually that you can almost talk yourself out of it right alongside the heroine, which is precisely the trap the film is building.

Mia Farrow, shrinking

The film belongs to Mia Farrow, and it works because of a single sustained physical idea in her performance: she gets smaller as it goes on. She begins as a bright, healthy young wife with a Vidal Sassoon crop and ends as a wraith, grey-skinned and skeletal, in constant pain she is repeatedly told is normal. Farrow lost real weight across the shoot and looks genuinely unwell in the later reels, and Polanski uses her frailty as a moral accusation aimed at everyone who keeps insisting she is fine. There is a party sequence, roughly two-thirds through, where Rosemary corners a group of younger women in the kitchen and finally says it aloud — that she is in agony, that her doctor will not help, that she is frightened — and for one scene the film lets someone believe her. It is the only oxygen in the picture, and Polanski snatches it back within minutes. The cruelty of that single reprieve tells you exactly what the film is doing. Every authority figure in Rosemary’s life — her charming actor husband Guy, the kindly elderly neighbours, the eminent obstetrician they steer her toward — closes ranks to tell her that her body is not telling her the truth.

That obstetrician, Dr Sapirstein, is the film’s masterstroke of everyday menace. Rosemary’s pain and her raw-meat cravings and her wasting away are all waved off with the paternalistic authority of 1960s medicine: don’t read books, don’t listen to your friends, trust me. The genius is that this is exactly how a real woman’s real symptoms were dismissed in that decade, so the supernatural conspiracy is indistinguishable from ordinary sexist medical practice. The audience knows something monstrous is happening. The film’s terror is that nothing about the way Rosemary is treated would look unusual to anyone watching from outside. Polanski keeps the camera at a discreet, well-mannered distance through these scenes, framing the medical dismissals as unremarkable social encounters, which forces the viewer into Rosemary’s exact predicament: you can see the wrongness, you cannot prove it, and every attempt to name it makes you look hysterical. The film weaponises the audience’s own politeness. We too keep hoping there is an innocent explanation, right up until there is not.

The coven as good neighbours

Ruth Gordon won a Supporting Actress Oscar as Minnie Castevet, and the win is instructive, because Minnie is the least gothic villain imaginable — a nosy, garish, over-friendly old woman in loud housecoats who bustles in with home-made chocolate mousse and cannot be got rid of. The coven of the Bramford are retirees and busybodies, and Polanski plays them almost entirely for social comedy, which is why they are so frightening. Evil here wears the face of the neighbour you are too well-mannered to be rude to. The satanic conspiracy operates through casseroles and unsolicited advice and drop-in visits, weaponising the ordinary courtesies that make it impossible for a nice young woman to say no.

Krzysztof Komeda’s score threads a wordless lullaby through the whole film, hummed by Farrow herself over the opening titles — sweet, cracked, slightly out of tune, a nursery rhyme with something rotten in it. Polanski’s camera does the rest of the work by withholding: doorways half-open, conversations heard through walls, key moments framed so that we see just too little to be sure. There is a shot down a hallway through a not-quite-open door that has been imitated for fifty years. The film trusts the audience to lean in and haunt itself. And William Fraker’s cinematography keeps the light bright and domestic throughout, so that the dread has no shadows to hide in and must instead seep out of ordinary rooms in daylight — a strategy Polanski would refine across his so-called Apartment Trilogy and one that quietly rewrote what a horror film was allowed to look like.

Where it comes from, and what it fathered

Levin’s novel sits in a specific American tradition of paranoid domestic fiction, and Polanski’s adaptation is the middle panel of what critics later called his “Apartment Trilogy” — the horror of the enclosed dwelling, the flat as a hostile organism. It is bookended by Repulsion, where a young woman’s sanity dissolves inside a London flat that seems to grow hands, and later by The Tenant. All three are studies of a mind or a body under siege in a room that will not keep the world out. Rosemary’s Baby is the most sociable of them and therefore the most insidious, because the siege is conducted with a smile.

The film’s living descendants are everywhere. The most direct is Hereditary, which lifts the whole structure wholesale — a family selected and cultivated by a coven of well-mannered strangers, a matriarch running the plot from the wings, a person destroyed by a conspiracy they were too polite and too gaslit to see. Ari Aster has been open about the debt. And the film’s core insight, that the scariest thing a horror film can do is make the audience watch a woman be disbelieved, runs straight into the folk-horror of The Witch, where a family’s refusal to believe the girl in their midst is the mechanism of their doom. Polanski found the template: isolate the heroine inside a consensus of reasonable people, and let the reasonableness do the killing.

The verdict

Rosemary’s Baby is the rare horror film that improves as its shocks lose novelty, because its shocks were never the point. The satanic reveal is almost anticlimactic by design; the real content is the two hours of accumulating dismissal that precede it, which have only grown more legible as audiences have learned to name what is being done to her. Farrow’s shrinking performance is one of the great pieces of horror acting, a study in a person being slowly convinced to distrust her own senses. And Polanski’s decision to shoot it all in warm daylight, in a beautiful apartment, among charming people, remains the film’s most radical choice — it located the genre’s future in the living room.

Watch it for Farrow and for Ruth Gordon’s monstrous good cheer. Then follow the apartment dread back into Repulsion, and follow the coven-cultivating-a-family idea forward into Hereditary, which is essentially this film with the lights turned off. The famous ending is below the line.

Spoilers below

The last scene is one of the most quietly devastating in horror, and it turns on the film finally granting Rosemary the belief it has withheld for two hours — at the worst possible moment.

Rosemary has been right the entire time. The pregnancy was engineered; her husband Guy traded her body to the coven in exchange for the acting career he wanted; the neighbours are Satanists; the baby is the son of the Devil. When she finally forces her way through the hidden door into the Castevets’ apartment, knife in hand, she finds the whole coven gathered around a black-draped bassinet, and the child inside it is hers. The horror of the finale is not the reveal — we have long since guessed it. The horror is the choice the film hands her.

Rosemary looks into the cradle, sees her son’s inhuman eyes, and recoils. And then she does not run, and she does not use the knife. The coven, sensing the maternal pull, invites her simply to be his mother — to rock him, to care for him. The final image is Rosemary approaching the black bassinet and beginning, tentatively, to soothe the crying baby, her revulsion softening into something like tenderness. The film ends on the appalling possibility that biology and love will win, that the woman who was betrayed by everyone will nonetheless mother the Antichrist because he is hers. Polanski refuses catharsis, refuses a rescue, refuses even a scream. He simply lets a mother reach into the cradle, and lets the audience understand that being finally believed has come too late to save her, and that she may not even want it to.
