Other Mommy
Starring Jessica Chastain, Other Mommy is a supernatural horror film about a young girl who encounters a frightening presence that resembles her mother. The story turns an everyday family setting into the centre of a disturbing mystery.
Released in US theatres on October 9, 2026, the film follows a young girl whose home life becomes increasingly frightening after she encounters an entity that looks like her mother.
Directed by Rob Savage, the film adapts Josh Malerman’s novel Incidents Around the House. Universal Pictures’ official announcement provides further details about the production and its release.
Beyond its unsettling premise, Other Mommy has attracted attention for its opening-weekend performance. It led the North American box office with an estimated $27.5 million and earned approximately $45.2 million worldwide in its debut. Here is what viewers should know about the story, cast, reported earnings and streaming outlook.
What Is Other Mommy About?
The story centres on Bela, a young girl living in a family affected by tension at home. Her situation becomes more disturbing when a supernatural presence appears and begins to resemble her mother. Bela calls the entity “Other Mommy,” but its familiar appearance makes it difficult to know what is safe and what is dangerous.
Bela cannot tell whether the figure that resembles her mother is someone she can trust. This uncertainty turns the family home, normally a place of comfort, into the setting for her growing fear.
Bela’s situation places her at the centre of a frightening problem: she must understand what is happening while relying on the adults around her. This family dynamic gives the supernatural threat a personal dimension.
Based on Josh Malerman’s Incidents Around the House, the film adapts the novel’s family-centred horror for the screen. Viewers can follow Bela’s story without reading the book, while readers can consider how the film interprets the original material.

Other Mommy Box Office: Opening Weekend Explained
Other Mommy opened strongly in North American theatres. According to the Associated Press, studio estimates put its domestic opening at $27.5 million from 3,365 theatres. The film also earned about $17.7 million internationally, bringing its reported worldwide opening to approximately $45.2 million.
According to the Associated Press box-office report, Other Mommy earned an estimated $27.5 million in its North American opening weekend.
The figures in this section are reported opening-weekend estimates. Actual totals may change as updated box-office data becomes available.
Box-Office Details
| Box-office detail | Reported figure |
|---|---|
| US theatrical release | October 9, 2026 |
| North American opening | $27.5 million |
| International opening | Approximately $17.7 million |
| Worldwide opening | Approximately $45.2 million |
| Reported production budget | Around $19 million |
| North American theatres | 3,365 |
The production budget is an estimate reported by the press, not a complete accounting of the film’s costs. The figures above should also be treated as a snapshot of the opening weekend; subsequent weekend results and final reported totals may change the picture.
Does the Opening Mean the Film Is Profitable?
The reported opening is encouraging compared with the estimated $19 million production budget, but it does not establish profitability. Cinemas retain part of ticket revenue, and marketing, distribution and other expenses affect the final result. A clearer assessment will require more complete financial information and the film’s performance over time.
Other Mommy vs The Social Reckoning
The same weekend offered a useful comparison between a supernatural horror film and a drama built around contemporary technology and social issues.
Opening-Weekend Comparison
| Opening-weekend measure | Other Mommy | The Social Reckoning |
|---|---|---|
| North American opening | $27.5 million | $5.5 million |
| International opening | Approximately $17.7 million | Approximately $3.5 million |
| Worldwide opening | Approximately $45.2 million | Approximately $9 million |
| Reported production budget | Around $19 million | Around $30 million |
The figures reported by the Associated Press show a clear difference in opening-weekend demand. Other Mommy earned substantially more in its debut and had a lower reported production budget.
The opening-weekend comparison shows which film attracted more initial ticket sales, but it cannot establish which release will ultimately be more profitable. That assessment requires longer-term box-office results and fuller financial information.
The opening suggests that Other Mommy attracted substantial initial interest, but its longer-term commercial performance will depend on how ticket sales develop after its debut.
Why Did Other Mommy Attract Attention?
Three elements help explain why the film had a notable opening, although they should not be mistaken for proven causes of ticket sales.
1. A Simple, Unsettling Premise
Bela’s fear begins with something deeply familiar: a figure that appears to be her mother but may not be who it seems. Bela faces a frightening dilemma: the person she sees resembles her mother, yet the encounter leaves her unsure whether she is safe. This uncertainty drives the film’s tension and makes her home feel less predictable.
2. A Recognisable Lead Performer
Jessica Chastain gives the film a prominent name in its marketing. Her dual role also connects directly to the story’s central source of unease: the difference between someone who looks familiar and someone who can be trusted.
3. A Comparatively Modest Reported Budget
With its production budget reported at approximately $19 million, Other Mommy began its theatrical run with a relatively modest cost base compared with many major studio releases. However, the production figure alone cannot determine its financial success because promotional spending, distribution expenses and the studio’s share of ticket revenue also matter.
The Associated Press also reported a D+ CinemaScore, indicating an unfavourable initial audience grade. This contrasts with the film’s strong opening-weekend figures, although neither measure alone can predict its longer-term performance.
When Will Other Mommy Be Available for Streaming?
As of October 12, 2026, the sources consulted for this article do not confirm a streaming launch date for Other Mommy. The film is in US theatrical release, so viewers looking for its digital debut should rely on announcements from the distributor or streaming platforms rather than unofficial date predictions.
Peacock may be a possible US streaming destination because of Universal Pictures’ distribution connection, but no specific platform or release date should be treated as confirmed without an official announcement. A digital rental or purchase release may also arrive before a subscription-streaming launch, but its timing should be verified when an official listing becomes available.
Availability can differ by country. Viewers in India and other international markets should check local digital storefronts and streaming services rather than assume that a US release schedule will apply worldwide.
