Other Mommy

Other Mommy follows young Bela, who forms a relationship with a sinister entity in her home that looks uncannily like her own mother. The premise draws her into a terrifying and increasingly dark world. The 93-minute runtime suggests a tight, contained horror story built around this one idea, though the facts here don't show how well it develops.

Jessica Chastain is credited as both Mommy and Other Mommy, so the film rests on her playing a familiar parent and an unsettling double. Arabella Olivia Clark carries the central role of Bela, and the story depends on her bond with the entity. Jay Duplass (Daddo), Karen Allen (Grandma Ruth) and Arian Moayed (Uncle Frank) fill out a recognisable supporting cast, but I can't say how much each is given to do.

Rob Savage directs, and the film comes from Blumhouse Atomic Monster and Spin a Black Yarn, so it is clearly built as a studio-backed genre piece. A single-location, family-centred scare story at 93 minutes should favour economy over sprawl. Whether the pacing and tension hold up is something the available facts can't confirm.

Patrick Jonsson composes the music. In a horror film about a child and a false parent, the score and sound design usually do much of the work of unsettling the viewer. No details of the score were available, so I'm not rating it beyond a neutral, modest mark.

A lookalike entity that must read as both comforting and wrong calls for careful craft, whether through effects, makeup or performance. The facts don't say how the film achieves this, so this score stays cautious and reflects no confirmed standout work.

The early external rating is 5.8 from only 152 votes, which suggests a mixed-to-middling start that could easily shift as more people watch. The mother-double premise should draw fans of psychological and creepy-child horror, and the Chastain name adds interest. There is no audience score, box office or streaming data yet, so wider reception is unknown.
