Based on Josh Malerman’s novel Incidents Around the House, Other Mommy is a supernatural horror film that arrived in theaters on October 9, 2026. It follows an eight-year-old girl who encounters a sinister presence that looks exactly like her mother Jessica Chastain.

Here’s where things stand, when you might be able to rent or stream it, and everything else worth knowing about Jessica Chastain’s latest horror film.

Also, ignore any site claiming to stream the full film for free right now. It is a theaters-only release, so those are not legitimate sources.
Is Other Mommy on Netflix?
Not yet. But it is expected to land there eventually. Universal films go to Peacock first, then move to Netflix for a set licence window under Universal’s deal with both services. Reports point to a Netflix arrival sometime in 2027, after its Peacock run.
Is Other Mommy Available on VOD or Digital Rental?
Not yet. Universal has not announced a digital release date.
But Universal is known for moving its horror films to digital fast. Its titles usually hit premium rental 17 to 31 days after theaters. One forecast puts Other Mommy on Apple TV, Prime Video and other stores on Tuesday, November 3, 2026. That would be just in time for the week after Halloween.
The safest move is to set alerts on JustWatch, Apple TV and Fandango at Home. They will notify you the moment a rental or purchase option goes live.
When will Other Mommy be available to stream?
On Peacock, most likely in mid-January 2027. Nothing is official yet.
The closest comparison is Blumhouse’s Black Phone 2. It opened in October 2025 and began streaming on Peacock on January 16, 2026, about three months later. Following the same path puts Other Mommy on Peacock around January 15, 2027.
| Window | Expected Date | Status |
| Theaters | October 9, 2026 | Confirmed |
| Digital rent or buy | Around November 3, 2026 | Prediction |
| Peacock (US) | Around January 15, 2027 | Prediction |
| Netflix (US) | Mid-2027 | Prediction |
| Sky Cinema / NOW (UK) | Around June 11, 2027 | Prediction |
The Peacock date could shift. Universal’s deal lets films stay up to 120 days before Peacock, which would push it to early February 2027 at the latest.

Who directed Other Mommy?
Other Mommy was directed by Rob Savage, the filmmaker behind the lockdown hit Host and The Boogeyman. Nathan Elston wrote the screenplay. James Wan produced through Blumhouse Atomic Monster.
The story comes from Josh Malerman’s 2024 novel Incidents Around the House. Malerman is best known for Bird Box. He also served as an executive producer.
What happens in Other Mommy?
Bela is an 8-year-old girl living in a house full of tension. Her parents’ marriage is falling apart. One night, a presence steps out of her closet. It looks and sounds just like her mother. Bela calls it Other Mommy.
At first, it seems lonely and gentle. Then it asks to be let into Bela’s heart. From there, it starts following her out of the bedroom, changing shape and tearing the family apart.
It’s a creepy setup in the tradition of Mama, which also starred Chastain. But the two films aren’t connected.

On Rotten Tomatoes, the film sits at around 17 to 20 percent with critics. The audience score is 47 percent. Opening-night crowds gave it a D+ CinemaScore, the same grade as Hereditary and Megalopolis.

Other Mommy Box Office Collection
Here is the twist. None of the bad reviews mattered on opening weekend.
Other Mommy opened at No. 1 with $27.5 million, well above Universal’s $20 million forecast. It added $17.7 million overseas for a $45.2 million global start. Two-thirds of the opening crowd was aged 18 to 34.
| Box Office | Figure |
| Thursday previews | $3.6 million |
| US opening weekend | $27.5 million (No. 1) |
| Global opening | $45.2 million |
| Worldwide total so far | About $78.9 million |
| Budget | About $19 million |
With a $19 million budget, the film out-grossed its production cost in its first weekend alone. For a low-cost Blumhouse horror, that’s a clear win.
Is Other Mommy Family-Friendly?
No. Other Mommy is rated R. It has disturbing imagery, violence and a child in constant danger. The doppelganger scares are built to unsettle, and some scenes are tough to watch. This one is for adult horror fans only.
