The first trailer for Other Mommy hit theaters this weekend as a pre-show attachment to The Odyssey, and horror fans did not see it coming. Audiences who filed in expecting Christopher Nolan's epic got a cold bucket of dread poured over them before the opening credits rolled.
Here's the thing: a theater-exclusive trailer drop is one of the oldest tricks in the horror marketing playbook, and it still works. Catch a crowd that came for something else entirely, hit them with a jump scare before their guard is up, and let social media do the rest. Blumhouse pulled it off almost perfectly.

What the trailer actually shows
Directed by Rob Savage, the filmmaker behind Host and The Boogeyman, Other Mommy centers on 8-year-old Bela, whose family is fracturing under the pressure of her parents' marital breakdown. Out of that domestic chaos crawls something worse: a doppelgänger entity the child names "other mommy," which emerges from her bedroom closet and begins terrorizing the household.
Jessica Chastain plays a dual role, and the cast around her is genuinely impressive. Jay Duplass (Backrooms), Dichen Lachman (Severance), Arian Moayed (Succession), and Karen Allen (Indiana Jones) all appear. That ensemble alone signals this isn't a throwaway genre entry.
The trailer had its first closed-door debut at CinemaCon earlier this year, but this weekend marked the first time general audiences saw it. The online version hasn't dropped yet, which is why the social media reaction is running entirely on firsthand accounts from people who caught The Odyssey in theaters.
The jump scare dividing the internet
The opening jump scare in the trailer is the flashpoint. Reactions split almost immediately into two camps.
On one side, audience members describing a genuine physical reaction: one post described it as something that "won't allow me to sleep for the foreseeable future." Another put it more directly, asking if anyone else had a very undignified reaction sitting in their theater seat. The consensus from that camp is that Savage nailed the execution.
On the other side, a contingent who found the same scare almost comedically oversized. "The first jump scare in the trailer for OTHER MOMMY is a contender for Worst Of All Time," one viewer posted, while another noted their group "could not stop laughing" at a particular Chastain moment in the clip.
That divide is actually a decent sign for the film. Horror trailers that generate genuine split reactions tend to drive ticket sales harder than ones that land uniformly. Nobody argues about a trailer they forgot the moment they walked out.
Why Rob Savage is the right director for this
Savage built his reputation on low-budget, high-concept horror. Host, his 2020 pandemic-era film shot entirely over Zoom, ran 57 minutes and became one of the most efficient horror films in recent memory. The Boogeyman, his first major studio production, proved he could scale up without losing the craft.
Other Mommy is a Blumhouse production, which means a bigger platform and a theatrical release date of October 9. That Halloween window is exactly where this kind of film belongs. The premise, a child's imaginary fear made physically real during a period of family instability, sits in well-worn horror territory, but Savage's track record suggests he knows how to find the specific angle that makes familiar material feel fresh.
What most players miss in the early buzz cycle for horror films is that the trailer reaction rarely predicts the final product accurately. A jump scare that divides a theater audience in July tells you very little about whether the film's third act holds together. The real test comes in October.
For now, the conversation is exactly where Blumhouse wants it: loud, divided, and spreading. If you're already tracking horror releases for the back half of the year, Other Mommy just moved up the list.
