Jessica Chastain in Other Mommy Trailer

The shadows are lengthening, and with it comes a chilling new cinematic event. Universal Pictures and Blumhouse Atomic Monster have just unveiled the first trailer for Other Mommy, a psychological horror/thriller set to hit cinemas on October 9th.

This isn’t just another jump scare; it promises a terrifying descent into the darkening psyche of a young girl named Bela. The story delves into a deeply unsettling relationship where Bela finds herself drawn into the presence of a sinister entity residing in her home—an entity that eerily mirrors the face of her own mother.

At the heart of this haunting narrative is the incredible performance of Oscar-winner Jessica Chastain, who takes on the demanding dual role of both Bela’s mother and the manifestation of this spectral entity. Her ability to navigate such complex emotional and psychological terrain sets the stage for a truly disturbing cinematic experience.

Guiding this descent into madness is director Rob Savage, known for crafting intense, atmospheric horror. He teams up with producer James Wan, celebrated for landmark films like The Conjuring and Saw, ensuring that the visual language of the film will be steeped in dread.

The foundation for this narrative was meticulously crafted by WGA award winner Nathan Elston, who penned the script based on Josh Malerman’s bestselling novel, Incidents Around the House. Malerman’s work, which famously inspired the smash-hit Netflix film Bird Box, provided the rich, unsettling framework for this new story.

The cast is stacked with talent, lending further depth to Bela’s world. Alongside Chastain, the film features Arabella Olivia Clark as Bela, Jay Duplass playing Bela’s father Daddo, Dichen Lachman, Arian Moayed, and screen legend Karen Allen, all contributing to a complex tapestry of familial dread.

Whether you are a fan of tightly wound suspense or deeply personal psychological horror, Other Mommy promises a voyage into the heart of fear. Prepare to let the shadows in—it arrives in theaters on October 9th.
