Other Mommy trailer: Jessica Chastain horror lands Oct 9

moviesJul 21, 202624336

Universal and Blumhouse released the first trailer and poster for Other Mommy, which opens in US theaters October 9, 2026. Directed by Rob Savage and written by Nathan Elston, the film adapts Josh Malerman’s 2024 novel Incidents Around the House. Jessica Chastain headlines as the titular figure, joined by Jay Duplass, Dichen Lachman, Sean Kaufman, and Karen Allen. The studio frames the film as a James Wan, linked horror thriller about a young girl named Bela who forms a relationship with a sinister entity in her home that looks uncannily like her own mother. Universal published the trailer and poster alongside the October release announcement; the marketing leans into maternal doppelgänger scares with the tagline "Your mommy won't save you."

The book this is based on, Josh Malerman's Incidents Around the House, was so scary I stopped 3 pages in to look up the end on Wikipedia. The dread was unbearable almost from page 1. I didn't finish it because the content is Not For Me, but holy SHIT was this scary. I hope the movie captures that.

I loved the book so much (easily one of the scariest novels of 2024) and can't wait to see this

Redd, your fav panda 🧡🤎🧡3

I'm not super into horror. But as a huge fan and lover of Coraline, this really grabs my attention and I just might go see it! ...not alone, of course! 😭

Hootin and hollerin at this

Apparently this trailer has been playing in front of The Odyssey recently. With that aside, pretty creepy trailer @mvbrat10.bsky.social @nerdobaggins.bsky.social @ryanjrobotham.bsky.social @bvlikeslinguica.bsky.social @gonzaegonza91.bsky.social @scalawagjack.bsky.social @thanosprime.bsky.social

I do wish they had stayed with the same title as the book this is based on, as the current title just makes me think of Coraline. Either way looks interesting. Just hope it's not infested with a bunch of loud noise jump scares like this trailer has 🙄

The trailer for this is wild

OMG, this looks SO GOOD. It's not often a trailer gives me goose bumps.

We have correctly deduced that we can make Neil Gaiman stories without Neil Gaiman

This Horror Renaissance is going VERY well indeeed. 💀

Mac Rogers2

By casting Chastain and changing the title from the book, they're definitely gonna fool a very small select group of people into thinking this is a bizarrely late sequel to MAMA.

certeza que vai ser bagaceira mas estarei assistindo e prestigiando

Omg I read the book (incidents around the house by Josh Malerman) and it was so scary. I can't wait for this movie! 🍿

Without seeing the trailer, this poster and the idea of Chastain in a horror already has my attention tbh.

I thought they missed with the title - how did they not go with "Other Mother" that's so pleasing to say. Also, the trailer looked very creepy and pretty good.

The Odyssey was excellent—no surprise. What DID surprise me was the FANTASTIC trailer for #OtherMommy, releasing 10.19.2026. @joshmalerman.bsky.social 's INCIDENTS AROUND THE HOUSE is getting its film treatment, and I cannot wait to see how it goes. That was my favorite book of 2024. #horrorsky

The Odyssey is a pretty good name for a movie about going on an odyssey but Other Mommy is a *perfect* name for a movie about having an other mommy.

Have not been able to stop thinking about the movie Other Mommy, specifically why they chose that title when Other Mother was right there.

My guess is it's because the Other Mother is the main antagonist in Coraline, which is popular enough that it'd be confusing (or maybe a copyright issue, idk). But the way that trailer lays out each letter after the other feels like a fake out and I don't know why. Ofc we're expecting the rhyme!!
