The weekend’s scariest opening is outperforming the weekend’s most prestigious one. Other Mommy, a horror film toplined by Jessica Chastain, collected a strong $3.6 million from Thursday previews starting at 2 p.m. across 2,850 theaters, before expanding to 3,365 screens for its opening day.
The film comes from director Rob Savage and is produced by James Wan’s Atomic Monster alongside Blumhouse — two of the most reliable brands in modern horror. Chastain plays the mother of a young girl, played by Arabella Olivia Clark, around whom the film’s supernatural dread gathers. Horror has repeatedly proven the most dependable theatrical genre of the post-pandemic era, and modest-budget entries from these producers have a habit of turning preview-night enthusiasm into profitable runs.
By contrast, the adult drama The Social Reckoning managed about $650,000 in previews. Both films are chasing Verity, the Colleen Hoover adaptation starring Anne Hathaway, Dakota Johnson and Josh Hartnett, which scored a $62.1 million worldwide debut — the author’s second-best global opening — and sits atop the North American chart.
The weekend also brings a footnote for the record books at the other end of the chart: the Tom Cruise feature Digger, priced at a reported $160 million, opened to $8 million domestically — the star’s lowest opening in 19 years. In October 2026, it seems, audiences are choosing jump scares and page-turners over star power.
How preview numbers shape an opening weekend
Thursday preview grosses are the first hard data point for a new release, but they are not a full forecast. Preview screenings start in the afternoon, draw the most motivated fans first and often include premium format surcharges. Studios watch the preview figure for momentum, while exhibitors watch how quickly auditoriums fill across the evening. A film that expands from a preview footprint to a wider screen count on Friday, as this one does, is effectively running two launches in two days.
Horror has a particular preview culture. Dedicated genre audiences tend to show up early, partly to avoid spoilers and partly because opening night atmosphere is part of the appeal. That front loading can flatter a Thursday number, so the more telling test usually comes on Saturday, when casual audiences decide whether word of mouth is strong enough to broaden the crowd beyond committed fans.
Why modest budgets change the math
The commercial logic of modern horror rests on contained costs. A film made for a modest budget does not need to dominate a weekend in order to become profitable; it needs a solid opening, a respectable second weekend hold and a long tail across international markets, premium video on demand and streaming licensing. That is why producers known for disciplined budgets can treat a strong preview figure as an early sign of profit rather than merely a good start.
The contrast with an expensive star vehicle is instructive. A production reported at a far larger budget must sustain high grosses for weeks, across many territories, to reach the same financial outcome. In a crowded October market, screens and audience attention are finite, and exhibitors reallocate both quickly toward whichever titles are converting interest into ticket sales.
What decides the weekend
Three factors usually settle a frame like this one. The first is the hold of the incumbent leader, which entered the weekend with chart position and audience awareness already established. The second is the Saturday performance of the horror title, which reveals whether preview enthusiasm was a fan event or a broader trend. The third is the staying power of the adult drama, a category that often builds slowly through recommendations rather than opening day urgency. By Sunday morning, the ranking will say less about prestige than about which kind of film audiences chose to see first.
