LOS ANGELES — Moviegoers who went to theaters expecting Christopher Nolan’s sweeping epic The Odyssey got an unexpected dose of horror before the film even began.
A trailer for Other Mommy, a supernatural horror movie starring Jessica Chastain, has become a viral talking point after startling audiences during screenings of The Odyssey. Viewers took to social media to describe the preview as genuinely frightening, with one particularly abrupt jump scare catching many people completely off guard.
The reaction was especially notable because audiences had arrived for a major adventure film rather than a horror movie. The sudden shift from a conventional preview lineup to disturbing imagery left some moviegoers joking that they needed emotional support after the trailer.
From quiet family scene to terrifying surprise
The trailer initially gives viewers little indication of what is coming.
It opens with gentle piano music as Chastain’s character arrives home and encounters her young daughter, who is carrying a carton of ice cream. The scene initially resembles the beginning of a family drama or even a commercial.
Then the mood changes dramatically.
The seemingly ordinary situation gives way to disturbing events and a sudden scare designed to make viewers jump. That contrast appears to be a major reason the trailer has generated such a strong reaction in theaters.
Some moviegoers said the preview was among the most startling trailers they had encountered, while others argued online that the scare was more amusing than frightening.
Social media amplified the reaction
The trailer quickly became a subject of discussion across social platforms, with audiences comparing their reactions and warning other viewers about what to expect.
Some complained that a horror trailer containing a major jump scare should not be shown unexpectedly before a mainstream movie. Others viewed the controversy as evidence that the studio's marketing strategy had worked.
The debate has also helped transform Other Mommy from a relatively unfamiliar upcoming horror film into one of the more talked-about previews of the summer.
A calculated marketing move?
The unusual placement appears to have been particularly effective because Other Mommy and The Odyssey are both associated with Universal Pictures.
Rather than releasing the trailer exclusively online, the studio first exposed large theater audiences to it in an environment where viewers were unlikely to be expecting a horror scare.
That strategy essentially turned audience reactions into free publicity. Once moviegoers began posting about their experiences, people who had never seen the trailer became curious about what had frightened everyone.
The studio subsequently released the trailer online, allowing audiences who missed the theatrical screenings to see what had caused the commotion.
Jessica Chastain takes on a darker role
Other Mommy stars Chastain in a story centered on a young girl who encounters a sinister supernatural presence.
The film is directed by Rob Savage, whose previous work includes horror projects such as Host and The Boogeyman. The cast also includes Jay Duplass, Dichen Lachman, Arian Moayed and Karen Allen.
The movie is scheduled for theatrical release on October 9, 2026.
The trailer may have already done its job
For a movie studio, few things are more valuable than audiences talking about a trailer without being prompted.
Whether viewers found the Other Mommy preview terrifying, ridiculous or simply unexpected, it succeeded in creating curiosity. The reaction also demonstrates the enduring power of theatrical marketing: a carefully timed scare can generate a level of conversation that a conventional online trailer release might struggle to produce.
For fans heading to see The Odyssey, however, the lesson may be simpler.
The epic journey of Odysseus might be the main event — but the real surprise could arrive before the opening scene.
