Where can you see the Other Mommy trailer right now?
For now, the Other Mommy trailer is theater-only. Audiences catching The Odyssey this weekend are seeing the first look before Universal posts it online. Coverage from both JoBlo and Dread Central says a wider digital drop is expected soon, possibly as early as next week.
That limited rollout is intentional. Dread Central’s report from an Odyssey screening argues the trailer’s biggest scare lands hardest the first time you see it, which is why studios sometimes hold footage off the web.
What is Other Mommy about?
The film follows eight-year-old Bela, whose home life is already strained by her parents’ troubled marriage. A sinister presence she calls “Other Mommy” emerges from her closet each night and repeatedly asks, “Can I go inside your heart?”
As Bela refuses, the visitor grows more aggressive and puts the whole family at risk. The premise has drawn comparisons to 2013’s Mama, another Chastain horror title built around a maternal entity haunting children.
According to Dread Central’s screening write-up, the trailer opens with Bela sneaking ice cream before Chastain’s mom character comes home. Playful banter turns strange as Mommy asks unsettling questions, including whether her daughter remembers where she came from. The cut then spirals into creepy, otherworldly imagery with strong J-horror echoes and doppelgänger body language that looks deliberately wrong.
Importantly, the preview does not play as a “only the kid believes” ghost story. The father witnesses what is happening, and the family appears to know something is horribly wrong—raising the stakes beyond a standard haunted-child setup.
Who stars in Other Mommy and when does it open?
Jessica Chastain headlines the Universal release. The cast also includes Jay Duplass, Dichen Lachman, Karen Allen, Sean Kaufman, Adam Silver, Carrie Dimaculangan, and Arabella Olivia Clark as Bela.
Rob Savage directs after Host and The Boogeyman. Nathan Elston, a Succession writer, penned the screenplay. James Wan is producing through Atomic Monster and Blumhouse, in association with Spin a Black Yarn. Savage and Malerman are among the executive producers.
Universal had originally slotted Other Mommy for May 8, 2026, then shifted it to October 9, 2026—a prime Halloween-season window for a supernatural chiller already generating early buzz from its Odyssey-attached trailer.
