Other Mommy sets theatrical release for October 9 2026 with Jessica Chastain
Supernatural thriller Other Mommy arrives in movie theaters on Friday, October 9, 2026, marking Universal Pictures’ major horror rollout for the fall box office. Directed by Rob Savage, the project adapts author Josh Malerman’s chilling novel Incidents Around the House after the studio shifted its premiere window from an earlier slot on May 8, 2026. Audiences first caught early footage during theatrical screenings of Christopher Nolan’s feature The Odyssey ahead of the broader promotional campaign.
While moviegoers initially had to visit cinemas to catch the first teaser, promotional materials subsequently expanded across digital platforms to reach a global horror audience. Studio distributors paired the cinematic preview with a comprehensive online push as anticipation grew across social networks. The rollout positioned the feature directly in front of genre enthusiasts preparing for the autumn entertainment schedule.
Rob Savage directs adaptation of Josh Malerman horror novel
The new production marks director Rob Savage‘s latest entry in supernatural filmmaking following his work on Host and The Boogeyman. His creative approach brings Josh Malerman’s acclaimed book Incidents Around the House to the screen, continuing the author’s track record of psychological suspense established with Bird Box. Malerman’s source material earned critical recognition for filtering domestic dread through a child’s vulnerable viewpoint.
Academy Award winner Jessica Chastain leads an ensemble that features Jay Duplass, Dichen Lachman, Karen Allen, Sean Kaufman, Adam Silver and Carrie Dimaculangan. Newcomer Arabella Olivia Clark co-stars as eight-year-old Bela, anchoring the emotional core of the household crisis. The production cast Chastain in dual capacities, allowing her to portray both the embattled mother and the entity stalking the family home.

Chilling premise centers on fractured family dynamics
Narrative events follow young Bela as she navigates mounting tension caused by her parents’ deteriorating marriage inside their home. Her domestic distress deepens when a malicious entity emerging nightly from her bedroom closet demands entry by asking, “Can I enter your heart?” As the child resists the repeated plea, the haunting escalates into overt hostility that threatens everyone under the roof.
Thematic elements of a monstrous surrogate mother pursuing vulnerable children naturally invite comparisons to Mama, the 2013 horror feature that also starred Jessica Chastain. That previous release demonstrated the actress’s affinity for maternal horror archetypes facing supernatural threats. The current adaptation deepens those psychological themes by binding the external terror directly to internal domestic collapse.
Blumhouse and Atomic Monster join forces behind the scenes
Producer James Wan oversees the feature through a partnership combining Atomic Monster and Blumhouse, working alongside production company Spin a Black Yarn for Universal Pictures. Executive production duties are shared by Rob Savage and author Josh Malerman alongside Michael Clear, Judson Scott, Macdara Kelleher and Ryan Lewis. Executive Alayna Glasthal handled creative oversight for Atomic Monster throughout physical production.
Screenwriter Nathan Elston, recognized for his work on the television drama Succession, adapted Malerman’s prose into the theatrical script. The film reaches commercial cinemas this Friday, October 9, 2026, securing a key premiere slot as movie theaters launch their seasonal Halloween programming.
