Other Mommy backdrop

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.
