If you caught The Odyssey in theaters recently, you might have already had the daylights scared out of you before Christopher Nolan’s epic even started. Universal Pictures pulled off a stealth marketing tactic by quietly dropping the first other mommy horror movie trailer in front of unsuspecting IMAX crowds. Designed initially like a cozy, heartwarming ice cream commercial, the preview delivered a sudden, bone-chilling jump scare that left entire auditoriums gasping.
Now that the official teaser is officially available online, horror film fans are dissecting every creepy frame. Headlined by Oscar-winner Jessica Chastain, the film looks primed to be one of the autumn’s most talked-about supernatural thrillers.
Here is the complete breakdown of Other Mommy, covering the storyline, source material, star-studded cast, and release details.
What is the Movie About?
The story revolves around an 8-year-old girl named Bela (Arabella Olivia Clark), who lives in a house filled with growing domestic tension. Things take a terrifying turn when a sinister entity living inside her closet begins connecting with her.
The twist? This entity takes on the exact look and voice of Bela’s real mother, Ursula.
Bela calls the presence “other mommy.” Throughout the film, the shapeshifter continually torments the child by repeating one disturbing request:
“Can I go inside your heart?”
As the entity creeps further into the family’s daily life, Bela’s real mother has to battle a twisted version of herself to save her daughter from being consumed.
Is “Other Mommy” Based on a Book?
Yes. The movie adapts the 2024 horror novel Incidents Around the House by Josh Malerman, the bestselling author behind Bird Box.
While Neil Gaiman’s classic Coraline also featured a sinister figure called the “Other Mother,” this project is a completely separate, hard-R adult supernatural story.
Cast Breakdown: Jessica Chastain’s Terrifying Dual Role
Taking on horror for the first time since IT Chapter Two and Mama, Jessica Chastain leads the film in a demanding double role. She portrays both Ursula, the protective mother trying to keep her home together, and the uncanny, monstrous doppelgänger lurking in the shadows.
She is joined by an impressive supporting cast across TV and film:
- Jessica Chastain as Ursula / “Other Mommy”
- Arabella Olivia Clark (The Housemaid) as young Bela
- Jay Duplass (Industry, Transparent) as Bela’s father, Daddo
- Dichen Lachman (Severance)
- Arian Moayed (Succession)
- Karen Allen (Raiders of the Lost Ark)

Universal and Blumhouse Atomic Monster put together a serious dream team of genre filmmakers for this project:
- Director: Rob Savage, who exploded onto the horror scene with the pandemic hit Host before directing Stephen King’s The Boogeyman.
- Producer: James Wan, the legendary architect behind The Conjuring, Insidious, and Saw.
- Screenwriter: Nathan Elston, an award-winning writer known for his work on HBO’s Succession.
