Jessica Chastain’s new horror movie trailer debuts with The Odyssey

Get ready to brace yourselves, because the supernatural horror world is getting a fresh, unsettling debut with Other Mommy. Universal Pictures has just attached the first trailer for director Rob Savage’s new thriller to theatrical screenings of Christopher Nolan’s The Odyssey, offering fans an exclusive glimpse into the adaptation of Josh Malerman’s novel, Incidents Around the House.

This isn’t just another ghost story; it delves into the strained dynamics of a family under siege by something far more sinister. The film follows Bela, an eight-year-old girl, whose home life is already fraught with tension when a terrifying presence known only as “Other Mommy” begins to manifest in her closet every night.

The entity doesn’t just scare; it demands attention, posing a chilling question that cuts straight to the core of fear: “Can I go inside your heart?” As Bela resists this supernatural visitor, the entity grows increasingly aggressive, placing her entire family in grave danger and forcing the young girl to confront an evil determined to shatter their fragile bonds.

The premise echoes classic horror tropes, drawing comparisons to films like Mama, which starred Jessica Chastain in a similar haunting narrative involving children and mysterious maternal entities. This lineage sets the stage for a deeply personal and visceral experience.

Jessica Chastain anchors this unfolding drama alongside a compelling ensemble cast, including Jay Duplass, Dichen Lachman, Karen Allen, Sean Kaufman, Adam Silver, Carrie Dimaculangan, and newcomer Arabella Olivia Clark, who portrays Bela. The chemistry among the actors promises to amplify the emotional stakes of the horror.

The creative foundation behind Other Mommy is equally robust. It was produced by Atomic Monster and Blumhouse in association with Spin a Black Yarn for Universal Pictures. Director Rob Savage and author Josh Malerman served as executive producers, bringing their unique vision to life alongside collaborators like Michael Clear, Judson Scott, Macdara Kelleher, and Ryan Lewis.

The screenplay was penned by Nathan Elston, a writer known for his sharp storytelling in the realm of high-stakes drama. This powerful combination of talent ensures that the supernatural elements are grounded in emotional reality.

Positioned perfectly for spook season, Other Mommy is slated for a theatrical release on October 9, 2026, giving audiences a prime opportunity to experience this adaptation during the Halloween movie season. The debut trailer, now playing exclusively before The Odyssey, is shaping up to be one of the year’s most anticipated supernatural horror releases.
