The first look at Universal Pictures’ Other Mommy arrived where horror often lands best: in a dark theater. The trailer played in front of The Odyssey last night, and it ended with a scare that hit the entire audience at once.
Jessica Chastain plays the mother in the film, which opens with a young girl sneaking ice cream for lunch before her mother asks whether she remembers where she came from. That is enough to set the trailer’s uneasy tone, but it is the final beat — the abrupt scare and the creepy, otherworldly imagery around it — that made the preview feel like an event rather than a routine tease. The film is scheduled to open in theaters on October 9.
That timing matters because Universal Pictures chose to show the trailer in theaters before putting it online, turning the preview into a shared jolt for people who were already in their seats for The Odyssey. It is a smart fit for a horror campaign built on surprise, especially for a film directed by Rob Savage, whose Host was a breakout hit. The trailer’s look also leans hard into J-horror influences, with effects that the article describes as phenomenal, and the result is a first impression that does more than hint at a movie. It announces one.
The remaining question is not whether the trailer works. It clearly does. It is what Other Mommy is beyond this eerie setup, and whether Universal keeps that first scare locked to theaters for long or lets the wider audience see it online next.
