I keep thinking about the way Jessica Chastain’s hands move in the trailer for Other Mommy. Not the way they clutch at her daughter’s shoulders in that first, too-tight embrace—though that’s unsettling enough—but the way they don’t move when she’s pretending to be something she’s not. There’s a stillness to them, a deliberate absence of the small, unconscious gestures that make a mother’s touch feel like home: the absentminded tuck of a stray hair behind an ear, the quick squeeze of a hand before letting go.
The Other Mommy doesn’t do those things. She performs them, like an actor reading lines off a teleprompter. And that, more than any contorted limb or guttural whisper, is what makes my skin prickle.
Rob Savage has always been good at making the familiar feel wrong. His breakout film, Host, turned the mundane act of a Zoom call into a descent into digital hell, and The Boogeyman twisted the childhood fear of the dark into something far more intimate and adult. With Other Mommy, he’s taking on the most sacred of domestic spaces—the mother-child bond—and warping it into something that feels like a fairy tale told by a feverish child.
The trailer teases a line that’s already lodged itself in my brain: "Can I go into your heart?" It’s the kind of question a monster asks when it’s not content to just scare you. It wants to live there.
The premise is deceptively simple: seven-year-old Bela (Arabella Olivia Clark) starts noticing that her mother, Ursula (Chastain), isn’t quite herself. There’s another version of her lurking in the corners of their home, a doppelgänger with too-wide eyes and a smile that doesn’t reach them. The Other Mommy doesn’t just want to replace Ursula—she wants to become her, to burrow into Bela’s trust until the girl can’t tell the difference between the real thing and the imitation.
It’s a setup that could easily devolve into camp, but Savage and screenwriter Nathan Elston (adapting Josh Malerman’s novel Incidents Around the House) seem determined to ground it in something painfully real. This isn’t a story about jump scares or gore; it’s about the slow, creeping horror of realizing that the person who’s supposed to protect you might be the thing you need protection from.
Buzz & Rumors
Public reportsJessica Chastain Faces a Mother’s Worst Nightmare in Other Mommy (2026)
Rob Savage’s upcoming supernatural horror Other Mommy is already generating buzz—not just for its chilling premise, but for the powerhouse talent behind it. Starring Jessica Chastain as a mother battling a sinister entity threatening her family, the film promises to blend psychological terror with the raw intensity of a parent’s worst fears. latestnetflix.com's view is that here’s what we know so far about the project, its origins, and the team bringing it to life.
A Haunting Adaptation
Other Mommy is based on Josh Malerman’s 2024 novel Incidents Around the House, a story that taps into primal fears of home invasion and parental helplessness. The plot centers on Bela, an 8-year-old girl whose family is already strained by marital problems when a malevolent presence emerges from her closet. She dubs the entity the “Other Mommy,” and its influence quickly escalates from eerie to outright dangerous 
. Chastain plays the mother, who must go to extreme lengths to protect her daughter from the supernatural threat .
Malerman, known for his work on Bird Box (another horror hit that became a cultural phenomenon), has a knack for crafting stories that linger in the mind long after the last page. The shift from page to screen under Savage’s direction suggests a film that will lean into atmosphere and psychological dread—hallmarks of both the director and the source material.
Rob Savage’s Vision for Horror
Rob Savage, the filmmaker behind Host (2020) and Dashcam (2021), has built a reputation for modern, tech-savvy horror that feels uncomfortably close to home. Host, in particular, became a pandemic-era sensation for its Zoom-based scares, proving Savage’s ability to adapt horror to contemporary settings. With Other Mommy, he’s stepping into more traditional supernatural territory, but given his track record, expect a fresh twist on the genre.
Savage’s collaboration with writer Nathan Elston (who penned the screenplay) and producer James Wan—horror royalty behind The Conjuring and Insidious—hints at a film that balances intimate family drama with large-scale scares . Wan’s involvement likely played a role in the film’s recent release date shuffle, pushing it to October 2026, a prime slot for horror films looking to capitalize on Halloween season .
A Stellar Cast Brings the Terror to Life
Jessica Chastain leads the ensemble as the mother at the heart of the story, a role that will no doubt showcase her ability to convey both vulnerability and fierce determination. Alongside her, Jay Duplass plays the father, adding another layer of tension to the family dynamic . Young actress Arabella Olivia Clark takes on the pivotal role of Bela, the girl who first encounters the “Other Mommy,” while Dichen Lachman, Arian Moayed, and Karen Allen round out the supporting cast .
The chemistry between Chastain and Duplass—who previously worked together in The One I Love (2014)—could add emotional depth to the film’s supernatural conflicts. Meanwhile, Lachman and Moayed, both known for their work in genre projects (Altered Carbon, Inventing Anna), bring experience with high-stakes storytelling. Karen Allen, a veteran of films like Raiders of the Lost Ark, adds gravitas to the ensemble.
**What’s Next for Other Mommy?**
As of now, details about the film’s production are scarce. There’s no word on whether filming has wrapped or if reshoots are planned, though the October 2026 release date suggests post-production is well underway . Given Savage’s history of innovative horror, fans are speculating about potential marketing strategies—could we see a viral campaign mimicking Host’s found-footage style, or will the studio lean into traditional scares?
One thing’s certain: Other Mommy is shaping up to be a must-watch for horror enthusiasts. With a gripping source material, a director known for reinventing the genre, and a cast led by one of Hollywood’s most compelling actresses, the film has all the ingredients for a standout entry in 2026’s horror lineup.
