Groundhog Day (1993) is not a horror film, but its first act is profoundly siniestro . Phil Connors wakes up to the same song, the same groundhog, the same man asking for a donation. The familiar has become a prison. The horror is not a monster but the realization that time itself has broken and is now a closed loop. Similarly, in Happy Death Day (2017) and the avant-garde masterpiece Last Year at Marienbad (1961), repetition strips away the comforting illusion of linear progress. We are left with the naked, repressed truth: we are trapped in our own traumas, repeating them until we die. Contemporary cinema has moved lo siniestro out of gothic mansions and into the mundane. The films of Yorgos Lanthimos ( The Killing of a Sacred Deer , Dogtooth ) create uncanny tension through emotional flatness, stilted dialogue, and domestic rituals gone wrong. A family dinner, a teenage romance, a doctor-patient relationship—these familiar social scripts are performed so rigidly that they become alien. The repression here is not of ghosts but of natural human empathy and emotion. When the father in The Killing of a Sacred Deer must choose which family member to kill, the cold, rational deliberation is more siniestro than any ghostly wail.
Likewise, Céline Sciamma’s Petite Maman (2021) inverts the uncanny: an eight-year-old girl meets her mother as a child in a parallel time. The encounter is gentle, but the premise is deeply uncanny. To see your parent as a peer, to recognize their childhood vulnerability, is to have the stable hierarchy of family—the most heimlich structure—dissolve into uncertainty. Lo siniestro in cinema is ultimately the art of the unhomely home. It is the mirror that reflects a face you do not recognize, the lullaby that becomes a scream, the childhood toy that watches you while you sleep. Unlike terror (which looks outward) or horror (which recoils from disgust), the uncanny turns inward. It asks us to consider that the deepest monsters are not aliens or demons, but the repressed versions of ourselves, our forgotten childhood beliefs, and our inescapable, repeating traumas. When we leave a truly uncanny film, we do not feel relieved. We feel a cold draft in the living room, a floorboard creak in a familiar hallway. For a moment, home is not safe. Home is where the repressed returns. And that, in the dark of the cinema, is the most siniestro feeling of all. lo siniestro pelicula
In The Others (2001), Nicole Kidman’s children believe the house is haunted by “intruders.” The twist—that the mother and children are themselves the ghosts—is a perfect uncanny inversion. The family home, the ultimate heimlich space, is revealed to be a tomb. The living are dead, and the dead are living. This returns us to the primitive, repressed belief in an afterlife, a belief we thought we had outgrown, now made terrifyingly literal. Groundhog Day (1993) is not a horror film,
Similarly, in Jordan Peele’s Us (2019), the Tethered are literal doppelgängers living in the underground of America’s unconscious. When Adelaide confronts Red, the film reveals that the “original” might be the copy and the copy the original. This is pure Freud: the repressed underclass of the self (trauma, violence, animal instinct) does not stay buried. It comes home, wearing your face, demanding recognition. Freud noted that one of the strongest uncanny triggers is the revival of infantile complexes—particularly the belief that the dead are still alive, or that inanimate objects have souls. Cinema weaponizes this through the figure of the uncanny child. Children are supposed to be innocent, familiar, safe. When they act with adult malice or supernatural knowledge, the familiar becomes monstrous. The horror is not a monster but the
In cinema, lo siniestro therefore requires a domestic or recognizable setting. A haunted castle is not uncanny; it expects ghosts. But a suburban living room, a childhood nursery, or a wedding photograph that begins to decay before your eyes—that is siniestro . The film does not introduce a new fear; it resurrects an old, buried one. Perhaps the most potent cinematic vehicle for lo siniestro is the double. When a character encounters their exact replica, they confront the repressed fear of their own mortality (the double as omen of death) or the repressed desire for a second chance at life. Roman Polanski’s The Tenant (1976) offers a masterclass: Trelkovsky, a lonely Polish immigrant, slowly assumes the identity of a previous tenant who committed suicide. He begins to see her face in mirrors, wear her clothes, and eventually recreate her fatal leap. The horror is not that he is possessed, but that his own identity was always fragile, a thin costume over a void. Lo siniestro here whispers: You are not who you think you are. You are the other.
More recently, Ari Aster’s Hereditary (2018) uses the miniature dioramas made by the artist mother as a meta-cinematic uncanny device. The dollhouse is a perfect replica of the real house—but as the film progresses, the boundary collapses. We realize the characters are not simply living their lives; they are figures in a supernatural script, being manipulated like dolls by a demonic cult. The familiar childhood act of playing with miniatures becomes siniestro when you suspect that you are the miniature. Freud famously described the “repetition compulsion”—the psychological drive to repeat traumatic events, even when they cause pain. In the uncanny, this compulsion becomes visible, mechanical, and inescapable. The looping narrative is therefore a quintessentially uncanny form.
In 1919, Sigmund Freud published Das Unheimliche , an essay that would forever alter the landscape of horror and psychological tension. Translated awkwardly as “the uncanny,” the Spanish term lo siniestro captures something more active: a creeping, unsettling wrongness that arises not from external monsters, but from the familiar turning against itself. Cinema, as the art of moving images and psychological identification, is the perfect vessel for lo siniestro . Unlike the jump-scare terror of a slasher or the revulsion of body horror, the uncanny in film operates on a quieter, more corrosive level: it makes us doubt our senses, our memories, and even our own identities. The Freudian Blueprint: The Homely Made Hostile Freud’s central thesis is deceptively simple: unheimlich (un-homely) is a subset of heimlich (homely, familiar, secret). Something becomes uncanny when a repressed childhood belief or primitive animistic thought suddenly reappears as a living reality. Freud lists specific triggers: the double (doppelgänger), involuntary repetition, animism, the evil eye, and the return of the dead. But the deepest uncanny, he argues, is the return of what should have remained hidden—specifically, repressed psychological content.
