Other Mommy Review: Jessica Chastain's Demonic Double Horror Falls 2026

In the new horror film Other Mommy, Jessica Chastain plays a mother whose demonic double terrorizes her family. The film, based on Josh Malerman's novel Incidents Around the House, aims to deliver psychological scares but ultimately falls short of being truly nightmarish.

Plot and Premise of Other Mommy

The story follows a family haunted by a sinister doppelgänger of the mother. While the concept is intriguing, the execution leaves much to be desired. The film builds tension but fails to sustain it, resulting in a series of missed opportunities for genuine horror.

Jessica Chastain's Performance

Chastain delivers a committed performance, but even her talents can't elevate the lackluster material. The dual role requires her to switch between loving mother and menacing entity, but the script doesn't provide enough depth to make either portrayal fully convincing.

Comparison to Other Horror Films

Other Mommy attempts to blend psychological terror with supernatural elements, but it lacks the finesse of classics like The Babadook or Hereditary. Here's how it stacks up:

Key Takeaways

• Other Mommy fails to deliver consistent scares despite a strong lead performance.
• The film's marketing created high expectations that the final product couldn't meet.
• Josh Malerman's source material is underutilized, resulting in a shallow adaptation.
• Horror fans may find the film derivative and lacking in originality.
