Jessica Chastain’s ‘Other Mommy’ Horror Trailer Stuns Viewers Ahead of ‘The Odyssey

Universal Pictures’ upcoming psychological horror film Other Mommy has sparked intense online debate after its disturbing trailer racked up over five million views in three days. Directed by Rob Savage and starring Jessica Chastain, the film adapts the 2024 novel Incidents Around the House, scheduled for theatrical release in October.

The Cinematic Jumpscare That Left Audiences Unprepared

Distributed by Universal Pictures, the marketing campaign for Other Mommy made an aggressive theatrical debut, playing directly ahead of screenings for Christopher Nolan’s historical epic The Odyssey. For many theatergoers, the tonal whiplash proved severe. The preview introduces an eight-year-old girl named Bela, played by Arabella Olivia Clark, who is hunted by a malevolent entity emerging from her closet. This entity assumes the form of her mother, played by Jessica Chastain, escalating tensions within the household.

Social media feeds quickly filled with startled reactions from viewers who encountered the preview unawares. On X (formerly Twitter), one moviegoer wrote, according to LADbible, about a specific shot: “WHEN THAT B*H WAS HIDING UNDER THE KITCHEN ISLAND. Holy st.” Another user remarked, “The trailer for the new Jessica Chastain movie played during our showing of the odyssey and please keep that tf away from me.” A third cinema attendee added, “My biggest takeaway from The Odyssey isn’t anything about The Odyssey itself. It’s the horror movie trailer that they showed right before for ‘Other Mommy’ that won’t allow me to sleep for the foreseeable future.”

Misdirection and Narrative Subversion in the Modern Horror Landscape

Audience disorientation extended beyond mere jump scares. Several filmgoers on Reddit noted that the trailer’s deceptive opening sequence initially led them to mistake the footage for a benign dairy advertisement. “When I first saw this trailer in theaters before The Odyssey the beginning had me thinking it was an ad for Turkey Hill ice cream – Mom and daughter would go into the kitchen and have ice cream for dinner and smile,” one Reddit user shared, according to LADbible. “Oh god was I wrong.”

Director Rob Savage explained his creative intent to Empire, noting that audiences are actively hungering for something new and subversive. The narrative examines a crumbling relationship between Bela’s parents, which provides an opening for the supernatural antagonist. Savage told Empire that the emotional journey of the mother-daughter dynamic operates in parallel with the Other Mommy’s psychological manipulation and gaslighting. The entity attempts to drive a wedge between Bela and her family, exploring the horror of deciding who to let into the home.

Production Background and Context

The film is based on the 2024 novel Incidents Around the House. While plot specifics remain heavily guarded ahead of the October release date, the project has already garnered early awards buzz. Meanwhile, the film it originally paired with in theaters—Christopher Nolan’s The Odyssey—runs for two hours and fifty-two minutes and was filmed at several locations in the Peloponnese, including Nestor’s Cave, Voidokilia Beach, Almyrolaka Beach on the island of Pylos, and Methoni Castle, according to documentation from the Hellenic Film Commission cited by LADbible.
