Jessica Chastain's Other Mommy Haunts Box Office With Forty-Seven Million Dollar October Opening

Jessica Chastain's supernatural horror thriller "Other Mommy" terrified its way to a commanding box office debut, earning forty-seven point seven million dollars through October 23 and claiming the number two spot among October 2026 releases. The Universal Pictures and Blumhouse production opened exclusively in theaters October 9 across three thousand three hundred seventy venues nationwide.

Directed by Rob Savage—the bold genre filmmaker behind "Host" and "The Boogeyman"—and produced by horror maestro James Wan of "Saw," "Insidious," and "The Conjuring" fame, "Other Mommy" delivers a psychological nightmare based on Josh Malerman's 2024 novel "Incidents Around the House." The film's October 9 release date represents classic Blumhouse strategy, landing the weekend before the mid-October corridor to capture a clear runway into Halloween season.

Chastain's Dark Transformation

The Oscar-winning actress underwent a striking transformation for the role, sporting a blonde bob that became a talking point during the film's promotional tour. During an appearance on "Jimmy Kimmel Live" the night before the film's opening, Chastain embraced her new look while discussing the character's unsettling presence.

Early trailers sparked viral attention for a peculiar cooking scene where Chastain's character places dry pasta directly into a pot and turns on the flame without adding water—a deliberately jarring detail signaling something sinister about the maternal figure at the film's center. Universal Pictures and Blumhouse Atomic Monster leveraged the bizarre moment in marketing materials, teasing audiences with the question: "All you have to do is say yes."

Horror's Hot Streak Continues

The film's strong opening extends a banner year for horror at the box office. "Other Mommy" trails only Amazon MGM Studios' "Verity" in October 2026 releases, which has earned sixty-eight point five million dollars since its October 2 debut. Meanwhile, Columbia Pictures' "Resident Evil" reboot continues its impressive run with one hundred fifty point seven million dollars total gross after opening September 18.

The ninety-three minute supernatural thriller co-stars Hayley Spelman and features a screenplay by Nathan Elston adapting Malerman's source material. Savage's direction builds on his reputation for crafting intimate horror experiences that blend psychological dread with supernatural menace.

Blumhouse's Strategic Timing

Universal and Blumhouse originally scheduled "Other Mommy" for a May 8, 2026 release before delaying to October 9—a move that proved prescient given the film's Halloween season appeal. The horror specialists at Blumhouse Atomic Monster, led by Jason Blum and James Wan's partnership, selected the October corridor specifically to maximize the film's seasonal relevance.

The delay also gave the production time to refine marketing around Chastain's unsettling performance and the film's central mystery. Preview audiences responded strongly to the psychological elements intertwined with supernatural scares, a hallmark of Wan's producing style dating back to his groundbreaking work on "The Conjuring" franchise.

As "Other Mommy" heads into its third weekend, the film's momentum positions it to become one of the year's most profitable horror releases. With Halloween approaching and strong word-of-mouth among genre fans, Chastain's demonic maternal figure looks poised to haunt multiplexes through the end of October and beyond.
