Other Mommy

Rob Savage returns to the horror genre with Other Mommy, a psychological chiller adapting Josh Malerman's novel. The film stars Jessica Chastain in a dual capacity as both Ursula, a mother struggling with domestic tensions, and the titular entity that haunts her family. Jay Duplass appears as Russ, the father attempting to maintain stability while the household descends into supernatural chaos. James Wan produces through Atomic Monster, bringing his signature atmospheric style to this adaptation of Malerman's work.

Set for release on October 8, 2026, the project represents a collaboration between Blumhouse Productions, Atomic Monster, and Spin a Black Yarn. Cinematographer Lowell A. Meyer captures the isolating atmosphere of the Miller family home, which serves as the primary setting for the narrative. The production remains in post-production with no official budget figures or box office projections available at this time. [editar]

The story begins with the Miller family moving into a large, isolated house where eight-year-old Bela starts hearing faint voices from within the walls. These whispers introduce themselves as Other Mommy, a version of Ursula who promises to be more playful and attentive than the real mother. Initially dismissed as imagination, the phenomenon escalates when physical objects move without cause and the architecture of the home seems to shift during the night. Hallways stretch unnaturally, and rooms rearrange themselves, creating a labyrinthine environment that traps the family inside their own fears.

Ursula soon realizes the entity is not merely a ghost but a parasitic spirit feeding on belief and affection. It mimics her voice and mannerisms with unsettling precision, exploiting the uncanny valley effect to terrify those around it. Bela becomes increasingly drawn to the illusion, finding solace in a world without rules or consequences. Meanwhile, Russ faces visions of his own inadequacy as a provider and protector, taunted by the entity regarding his failures in the marriage. The tension builds as the line between reality and the entity's false paradise blurs, forcing Ursula to confront the possibility that she cannot simply outsmart a force operating within the child's mind.

Russ attempts traditional protection methods like salt lines and iron barriers, but these measures fail against an enemy that thrives on psychological vulnerability. The entity preys on Bela's loneliness and desire for unconditional acceptance, offering a seductive alternative to the strictures of parental love. As the haunting intensifies, Ursula discovers that the spirit requires verbal consent to fully possess the child. She races against time to reclaim her daughter's trust before Bela agrees to let the other mother in, realizing that saving her child means facing the terrifying reflection of her own maternal insecurities.[editar]
