Jessica Chastain’s double‑take will make you think twice about bath time.

A fresh trailer for Rob Savage’s upcoming horror "Other Mommy" drops the mask on Jessica Chastain’s unsettling dual performance – she plays both a loving mother and a nightmarish doppelganger that haunts her daughter Bela. The new footage leans into the creep factor, turning an innocent bubble‑bath scene into a chilling showdown and swapping a kiddie ball pit for something far less playful when the Other Mommy decides to join the fun. Savage, known for "Host" and "The Boogeyman," adapts Josh Malerman’s novel "Incidents Around the House" for the screen. The film pairs Chastain with Arabella Olivia Clark, who steps into Bela’s shoes, and is backed by a supporting cast that includes Jay Duplass, Dichen Lachman, Arian Moayed and Indiana Jones veteran Karen Allen. Producer James Wan adds his horror pedigree to the mix, promising a blend of child‑level terror and adult dread. While the trailer nods to recent genre hits like "Obsession" and "Backrooms," "Other Mommy" carves its own path with a story that escalates from eerie mimicry to outright aggression as the creature pursues its own agenda. Fans can expect the full nightmare to hit theaters on October 9, turning everyday family moments into something truly terrifying.

Chastain faces off with herself in the chilling new horror ‘Other Mommy’ – trailer drops!

Universal Pictures and Blumhouse’s Atomic Monster have just rolled out a second trailer for the upcoming horror‑thriller Other Mommy, slated to hit theaters on October 9. The film plunges viewers into the unsettling world of young Bela, who begins an eerie bond with a dark entity that mirrors her own mother’s visage. Oscar winner Jessica Chastain tackles a double‑duty, portraying both Bela’s mother and the sinister doppelgänger that haunts their home. She’s joined by Arabella Olivia Clark as Bela, Jay Duplass as the bewildered dad Daddo, and a supporting lineup that includes Dichen Lachman, Arian Moayed and legendary Karen Allen. The unsettling tone is shaped by director Rob Savage, known for Host and The Boogeyman, while horror heavyweight James Wan—behind The Conjuring and Saw—serves as producer. The screenplay, penned by WGA award‑winner Nathan Elston of Succession fame, adapts Josh Malerman’s New York Times bestseller Incidents Around the House. Malerman, whose novel Bird Box became a Netflix smash, brings his knack for dread to the screen, with executive producers Michael Clear, Judson Scott, Rob Savage, Malerman himself and Ryan Lewis overseeing the project.

‘IT’ Star’s New Horror Movie Is Officially Critics’ Worst Nightmare
Image via collider.com,

Jessica Chastain’s new horror, ‘Other Mommy,’ opens to a crushing 17% on Rotten Tomatoes.

Rob Savage’s latest horror, ‘Other Mommy,’ arrives with a marquee‑level lead—Academy‑Award winner Jessica Chastain—and a source material pedigree, adapting Josh Malerman’s 2024 novel Incidents Around the House. The film was billed as the next big financial horror smash of 2026, hoping to ride the wave of genre blockbusters that have dominated the box office this year. But the early critical response is anything but hopeful. With the embargo lifted just before its weekend debut, reviewers have already slashed the film’s Rotten Tomatoes average to a dismal 17%, making it the lowest‑rated horror of the season. The stark contrast is glaring when set against the year’s runaway success Obsession, which has become the highest‑grossing original horror of the century. Industry buzz had been high, especially after the genre’s recent triumphs—Curry Barker’s breakout debut and the record‑breaking runs of titles like The Substance and Weapons. Yet ‘Other Mommy’ seems to be the outlier, struggling to convince critics that its blend of psychological dread and supernatural menace lands any better than its promotional hype. If the film can still tap into the lucrative horror market remains to be seen, but the early numbers suggest it will have an uphill battle to shed its poor reviews and find an audience beyond the curiosity of Chastain’s fan base.

Jessica Chastain’s newest horror is already a critical disaster, scoring just 17% on Rotten Tomatoes.

Rob Savage’s upcoming thriller Other Mommy entered the spotlight with high expectations – a Universal release, a James Wan production, and a lead performance by Academy‑Award winner Jessica Chastain, based on Josh Malerman’s 2024 novel Incidents Around the House. Yet the early wave of reviews has been unforgiving, slamming the film as a "masterfully cringe mess" and dubbing it Chastain’s worst movie in years. The backlash is starkly contrasted with the genre’s current champion, Curry Barker’s Obsession, which has shattered box‑office records and earned a place among the highest‑grossing horror titles of the century. While Obsession enjoys rave reviews and awards buzz, Other Mommy languishes with a meager 17% average on Rotten Tomatoes, signaling a disconnect between its star power and audience reception. Critics have taken particular aim at the film’s premise – a sinister doppelganger stalking a child – calling it “stupid and unscary.” Despite Chastain’s committed performance, the consensus suggests the supernatural thriller fails to deliver the tension and originality that horror fans crave, casting doubt on its prospects as the year’s next financial horror smash.
