Other Mommy Review: Chastain Doubles Up in a Spooky, Familiar Chiller

This Other Mommy review starts with a simple question: what if the comforting face at your bedside isn't your mother's? Rob Savage's horror film, written by Nathan Elston, builds a haunted-house story around that unsettling idea. It stars Jessica Chastain in a double role.

Other Mommy Review: The Story So Far (No Spoilers)

The Other Mommy plot centers on Bela (Arabella Olivia Clark), a young girl growing up in a house with some quiet family tensions. Her father, called Daddo (Jay Duplass), handles most of the day-to-day parenting. Her mother is busy making a living and often out of the picture.

Into that gap steps something strange. A presence in the home looks exactly like Mommy, and it is eager to give Bela the attention she craves. Bela starts to form a relationship with it, and the film follows how that bond turns darker.

The setup recalls classic horror movie reviews territory, and one viewer compared it to Poltergeist. The difference is that the adults here take the child seriously fairly quickly, which keeps the story moving instead of stalling on disbelief.

What Works in Other Mommy

The core idea is effective. A monster that borrows a mother's face turns a safe figure into a threat, and the film uses that discomfort well.

• Atmosphere: Savage keeps the house tense and the scares fairly spooky.

• Pacing: At 93 minutes, the film doesn't overstay its welcome.

• Believing the child: Skipping the usual "nobody listens" routine feels refreshing.

Audience reactions suggest the violence lands harder because the film has built emotional stakes first. It is rated R, so expect some intensity.

Other Mommy Cast and Performances

The Other Mommy cast is led by Jessica Chastain, who plays both Mommy and Other Mommy. The role invites contrast between warmth and menace, and it gives the film its main hook.

Arabella Olivia Clark carries a lot as Bela. A horror story about a child lives or dies on whether we believe her loneliness, and she makes it credible. Jay Duplass brings an easy, lived-in presence as Daddo.

The supporting players include Karen Allen as Grandma Ruth, Arian Moayed as Uncle Frank and Dichen Lachman as Lois Anthony. They add texture to the family circle, though the story stays focused on the central trio.

Where Other Mommy Stumbles

The biggest problem is familiarity. Haunted closets, lonely kids and evil doubles are well-worn ideas, and the film rarely pushes them somewhere surprising. Some viewers will guess where it is heading.

The emotional theme of a child feeling neglected is clear from early on, and it is not explored with much depth. Audience scores sit around the middle (5.8/10 on TMDB from 182 votes), which fits a film that is competent rather than daring.

The jump from setup to nightmare can also feel mechanical. Strong ideas arrive, but they don't always grow into something more than a good premise.

Is Other Mommy Worth Watching?

Yes, if you want a short, creepy and well-acted horror film, though it won't redefine the genre. The Other Mommy release date is October 7, 2026, which makes it a handy pick for the spooky season.

Chastain's dual role and a tidy runtime are real draws. The scares are solid, and the premise sticks. What you won't get is much originality, so lower your expectations for fresh twists.
