Other Mommy Review – Jessica Chastain Can’t Exorcise a Familiar Haunting
Other Mommy review: Jessica Chastain anchors a horror story about the most frightening person in the house
A child saying that something is wrong at home is one of horror’s simplest and most effective alarms. Other Mommy builds its October scare around an especially intimate version of that fear: eight-year-old Bela sees a sinister presence that looks and sounds like her mother. Jessica Chastain plays Ursula, the real mother, as well as the doppelganger, while Rob Savage directs a 93-minute supernatural horror film from Nathan Elston’s screenplay.
The setup gives the film an immediate visual hook and an emotional question. Bela is a child who cannot easily make adults believe what she sees; her parents, Ursula and Russ (Jay Duplass), must decide how to respond as the presence becomes more threatening. The fear is not only that a creature has entered the home. It is that a familiar face and voice can no longer be trusted. When the person meant to make you feel safe may be the danger, ordinary family space turns strange.
Chastain is a strong reason to be curious. She can shift from parental warmth to a composed, uncanny stillness, and the double role lets the film play with recognition. Arabella Olivia Clark carries the child’s point of view, while Duplass gives Russ the practical problem of protecting his daughter without fully knowing what she is facing. Dichen Lachman and the supporting cast help fill out the family’s wider orbit.
The film has a clear horror lineage: a child, a home, an unseen or imitated presence, and adults who must confront how much of the danger is supernatural and how much is already present in the family’s emotional life. It is a familiar framework, which is both its comfort and its limitation. The premise can be understood quickly; the harder task is giving it a fresh rhythm and developing the relationships enough that the scares carry more than shock.
Release-day critical response has been mixed to negative, with critics noting Chastain’s commitment and some effective jolts while questioning the film’s originality and uneven execution. That gives the movie an interesting viewing proposition: its central idea is more unnerving than some of the material built around it. Horror fans may enjoy the fast-moving haunted-house experience, though viewers hoping for a deeply unsettling family drama may want more patience and psychological detail than the film supplies.
This review is spoiler-free and focuses on the setup, performances and craft rather than the final turns. If you want a new October horror release with a recognizable star, a child’s-eye perspective and an unsettling maternal double, Other Mommy has enough to make you lean toward the screen. Whether it leaves you uneasy after the credits is another question. Let’s get into it 👇

What Is Other Mommy About?
Other Mommy centres on Bela, an eight-year-old who encounters a supernatural presence that resembles her mother. The entity is not a vague shadow at the edge of a corridor: it can copy the appearance and voice of Ursula, the person Bela knows best. That familiarity changes the premise from a standard monster-in-the-house story into a problem of recognition. When Ursula appears, Bela and the audience have to consider whether the person in front of them is really her.
The family at the centre includes Bela, Ursula and Russ, her father. The film’s setup places their relationships under pressure as the entity’s attention becomes more frightening. Bela has to communicate an experience that adults may dismiss or interpret as a child’s fear. Russ is caught between taking his daughter seriously and trying to understand a threat that does not obey ordinary rules. Ursula’s double presence makes the mother-daughter relationship the story’s emotional and visual centre.
The home is important because it should be a place of routine and protection. Bedrooms, corridors and family spaces become uncertain once Bela believes the entity can approach her there. Horror often makes a house frightening by changing how the audience reads familiar rooms; here, the deeper trick is that the danger can borrow the face of a parent. That means a reassuring voice can become a warning, and a familiar gesture may no longer settle the child.
Rob Savage directs from Nathan Elston’s screenplay, with James Wan among the producers. The movie is a supernatural horror release from Universal, Blumhouse and Atomic Monster, with a reported 93-minute runtime and an R rating. It is based on Josh Malerman’s novel Incidents Around the House, though the film’s screen version should be judged on its own choices rather than on a reader’s expectation of a scene-by-scene adaptation.
The spoiler-free premise is enough to understand the central stakes: Bela’s safety, her parents’ ability to protect her, and the family’s capacity to trust what it sees. The movie’s most promising idea is also its most uncomfortable one. A child’s fear can be ignored, but this fear has the shape of the person everyone else trusts.
The Story and Plot
The story begins from a small domestic fear and lets it grow into a family crisis. Bela’s encounter with Other Mommy gives the movie a clear inciting event, but the more interesting development is how the adults respond. A supernatural threat is frightening; a child being unable to convince her parents that the threat is real can be just as tense.
The plot has to balance two kinds of uncertainty. The first is practical: what is the entity, what does it want, and how close is it to Bela? The second is emotional: what is happening inside this family, and why does the story place the mother-daughter bond under such scrutiny?
The child’s perspective creates a particular pacing challenge. Bela cannot always explain what she has seen in adult language, and the audience may know more than the adults while still not knowing the full rules of the entity. That can create productive dramatic irony. It can also become frustrating if the film repeats disbelief or warning scenes without changing the situation.
The movie’s fast pace is useful for an October crowd-pleaser. It does not ask viewers to wait a long time before the premise becomes clear, and the 93-minute length makes it an accessible night-out choice. The downside is that speed can crowd out development.
The Cast and Performances
Jessica Chastain carries the most demanding performance task because she must make two closely connected figures legible. Ursula needs to feel like a mother Bela could depend on, while Other Mommy needs to make that same familiarity uncomfortable. The contrast cannot rely entirely on makeup or an ominous musical sting. It has to emerge through posture, voice and the way the character occupies a room.
The distinction between warmth and threat is most effective when it is subtle. An imitation that is almost right can be more unsettling than one that is obviously monstrous. Chastain can hold a gaze or still her expression in a way that makes ordinary maternal behaviour feel slightly wrong.
Arabella Olivia Clark has a demanding job as Bela. A child protagonist in horror needs to be frightened without turning every scene into a single note, and needs to make the danger understandable even when she cannot explain all of it. Clark’s point of view provides the film with its emotional access.
What Works Best
The premise is immediately effective. A supernatural entity that looks and sounds like a child’s mother turns a familiar household into a place where affection and danger can wear the same face.
Chastain’s dual role is the film’s clearest asset. She has the range to make the audience read small differences in the two presences, and her restraint helps the character remain more unnerving than a performance that pushed every moment toward a theatrical monster pose. The film gives her a good horror vehicle, even if not every scene uses it to its full potential.
The focus on Bela’s perspective also gives the story a meaningful emotional anchor. Adults in horror often become the people who explain or deny what a child sees; a film that stays close to the child can make the room feel larger and the threat harder to control. Bela’s inability to guarantee that adults will respond in time creates tension that is different from a simple monster chase.
The short runtime is another advantage. At 93 minutes, the film is an easy recommendation for viewers looking for a new theatrical horror release without committing to a sprawling mythology or a long franchise entry. Its setup is clear and its tone is accessible to people who enjoy haunted-house stories.
What Doesn’t Quite Work
The main problem is that a potent premise does not always produce a distinctive film. The child-and-entity setup has been explored in many forms, and Other Mommy needs more than a convincing double to separate itself from familiar haunted-house releases. Some scenes reach for the same sudden noises, threatening appearances and delayed explanations viewers will recognise from other supernatural horror movies.
Pacing is a frequent concern in the early critical response. The movie moves quickly, but briskness is not the same thing as momentum. If scenes arrive before the emotional result of the previous scare has settled, the audience may register the sequence as activity rather than mounting dread. The story could use more quiet time with Bela and her parents, so that ordinary family behaviour becomes part of the atmosphere.
The tone can also feel uneven. The film wants to be a frightening supernatural story and a family drama about the pressures inside a home. Those strands should deepen one another, but they can feel like separate tracks when the scares become broad or when emotional scenes are cut short to keep the plot moving.
Characters and Relationships
Bela and Ursula’s relationship is the emotional centre of the story. The fear of Other Mommy is tied to the fact that the entity copies someone Bela loves and depends on. That connection gives the title its force: the danger does not arrive as a stranger in the woods, but as a presence that can use the family’s most familiar relationship to get close.
A child’s dependence changes the stakes. Adults can decide to leave a frightening house or call for help, at least in theory; Bela has to rely on the very people whose response she cannot control. The movie uses that vulnerability effectively whenever it shows her trying to explain what she sees. The audience can understand the fear even if it cannot yet determine the rules of the entity.
Russ’s position is more complicated than a simple skeptic role. He wants to protect his daughter, but he is trying to make choices with incomplete evidence. Parents often have to judge between a child’s certainty and the facts they can observe; in a supernatural story, that ordinary responsibility becomes impossible.
Ursula is difficult to discuss without touching the film’s mystery, but her double role raises a question about the difference between appearance and care. A face can be copied; affection cannot be proven by resemblance alone. The movie’s strongest scenes use that tension to make ordinary gestures—calling a child by name, approaching a bedroom, offering comfort—feel uncertain.
The wider family environment could be developed more. The presence of Dichen Lachman, Arian Moayed and other supporting players hints at social and family pressures beyond the immediate supernatural threat. Those details are important because horror works best when it reveals something that was already uncomfortable. The film gestures toward such complexity but does not always stay with it long enough.
The relationships are clear and relevant, especially the parent-child bond and the trust between Bela and Russ. They are less layered than the premise could support. A little more time spent on the family’s everyday closeness would have made the disruption of that closeness even scarier.
Visuals, Music and Atmosphere
Other Mommy’s visual world depends on familiar domestic spaces becoming uncertain. Bedrooms and hallways are useful horror locations because they belong to routines and vulnerability. A child’s room should be a place to sleep; a parent’s appearance should be reassuring. The film’s premise makes those spaces and signals suspicious, and that simple shift is one of its most effective craft ideas.
Rob Savage’s direction is most persuasive when it lets the camera hold on a room long enough for the audience to question what it sees. The entity’s resemblance to Ursula makes framing and eyelines matter. A face appearing in an ordinary place can become frightening because the audience recognises it before it understands why something feels wrong. The film has a few moments that use this well.
The editing is quick, matching the story’s brisk pace and keeping the supernatural threat visible. That approach supports a straightforward theatrical horror watch, but it can also undercut suspense. Horror often depends on the beat before a scare, not just the scare itself. When a cut arrives too soon, or the scene moves rapidly to another reveal, the image has less time to settle into the viewer’s imagination.
Themes and What the Story Is Really About
The film’s most accessible theme is trust. Bela has to decide whether the face she sees is the person she knows, and the adults have to decide whether they can trust a child’s account of something impossible. Familiarity usually brings comfort; here, it becomes a source of doubt. The supernatural premise makes a child’s question about her mother into a larger question about how people know one another.
It also explores the loneliness of not being believed. Bela’s fear is not simply that a presence may hurt her; she cannot guarantee that the people around her will recognise the danger in time. That is a powerful horror idea because it places the character in a position of dependence. A child can be sure of what she has seen and still have little power to make an adult act.
The mother-daughter relationship is another theme, though the movie’s supernatural hook can sometimes overshadow its emotional detail. By turning Ursula into both a source of care and a face that may be imitated, the film asks what makes parental love real. Is it the face, the voice or the choices a person makes?
Is Other Mommy Worth Watching?
Other Mommy is worth considering if you want a brisk October horror film, enjoy haunted-house stories and are curious to see Jessica Chastain in a double role. The premise is immediately understandable and the lead performance gives the film its clearest point of interest. At 93 minutes, it is an easy cinema choice for a night when you want supernatural scares without a long runtime.
The film is less likely to satisfy viewers who want slow-burn dread, a highly original mythology or a deeply developed family drama. Its central image is stronger than some of the plotting around it, and release-day reviews have raised reasonable concerns about familiar scares and uneven pacing. If you have already seen many recent child-haunting movies, you may recognise its moves early.
It is not necessary to know Josh Malerman’s novel Incidents Around the House before watching. The film can be approached as a standalone horror story, though readers may naturally compare the adaptation’s choices with the book. If you are looking for an accessible Halloween season pick, it may work better as a group watch than as the year’s defining psychological horror film.
My recommendation is to go for the premise and Chastain, with expectations calibrated for a familiar genre ride rather than a groundbreaking one. People who respond strongly to the idea of a loved one being copied may find the concept alone unsettling. People who need every scare to feel new may be more critical of the result.

Final Verdict
Other Mommy has a first-rate horror hook: a child sees a supernatural presence that can imitate the person she trusts most. That premise is easy to understand and hard to shake, and Jessica Chastain gives the movie a star performance with the potential to make familiar domestic gestures unnerving. Arabella Olivia Clark’s child-centred perspective and Jay Duplass’s grounded father also give the story a clear emotional foundation.
The film does not consistently build on those strengths. Its pacing can move past the moments that need room to breathe, the scares sometimes follow familiar patterns and the family drama is not developed as fully as the central idea suggests. The result is a horror release with memorable ingredients and a less distinctive overall shape.
I would recommend it to viewers who enjoy supernatural family horror and want a new theatrical option for October. I would steer people seeking a more patient, formally inventive or psychologically complex film toward other choices. Chastain’s role and the mother-double concept are the strongest reasons to watch; the uneven execution is the reason the movie stops short of being a standout.
The idea at the centre of Other Mommy understands that the most frightening face in a house may be the one everyone already knows. The movie does not always make that fear last, but when the premise is working, it makes an ordinary home feel like a place where trust itself has become dangerous.
⭐ Review Score: 5/10
A strong, creepy premise and a committed Jessica Chastain performance are undermined by familiar scares and uneven storytelling.

Conclusion
The most effective part of Other Mommy is the discomfort built into its central image. A child sees her mother’s face and cannot be sure that the person behind it is her mother. That idea turns trust, parental protection and familiar family spaces into horror material, and Jessica Chastain gives the film a performance worth watching.
The movie is less successful when it rushes past the family detail that could make the scares matter. Some of its devices will feel familiar to viewers who watch a lot of supernatural horror, and the emotional story does not always get enough room to become as unsettling as the premise. Still, its runtime and clear concept make it a straightforward genre-night option.
If you enjoy haunted-house stories, child-centred horror and Chastain’s work, you may find enough here to recommend it. If you prefer original mythology and patient dread, it may not be the October release you are waiting for. Did the mother-double premise work for you, or did the familiar scares take you out of the story? Share your reaction and score.
