«Other Mommy» Scares Up $12.6 Million Opening Day as Horror Dominates 2026 Box Office
Universal and Blumhouse-Atomic Monster's supernatural thriller «Other Mommy» earned $12.6 million on its first day and is tracking for a $27.5 million opening weekend. «The Social Reckoning» debuted to a soft $2.15 million on Friday.
«Other Mommy» is proving that horror's grip on the 2026 box office is far from loosening. The Universal Pictures release, produced by Blumhouse-Atomic Monster, pulled in $12.6 million on its opening day and is now on track for a $27.5 million debut weekend across 3,365 domestic screens, according to industry estimates.
The supernatural thriller stars Jessica Chastain in dual roles and was directed by Rob Savage. It hails from producer James Wan, whose Blumhouse-Atomic Monster banner has become a reliable engine for mid-budget scare fare. The film's strong start comes despite scathing reviews from some critics, suggesting that the horror audience is turning out on brand loyalty and Halloween-season appetite rather than critical praise.
«Other Mommy» arrives amid an extraordinary run for the genre. Major 2026 openings including «Obsession,» «Backrooms» and «Resident Evil» have already demonstrated that horror is one of the few categories consistently drawing crowds to theaters. With Halloween approaching, that momentum shows no sign of slowing, and the weekend's top spot was never seriously in doubt once Friday numbers came in.
The weekend's other wide debut, «The Social Reckoning,» had a far rougher reception. The film opened to just $2.15 million on Friday and is projected to finish the weekend with around $6 million — a disappointing result that suggests it failed to connect with audiences in the same way. The title's weak start stands in sharp contrast to the robust performance of «Other Mommy,» underscoring how uneven the current theatrical marketplace remains for non-horror releases.
For Universal and Blumhouse-Atomic Monster, the opening validates a strategy of releasing modestly budgeted thrillers with recognizable stars and strong genre hooks. Chastain's dual performance gives the film a prestige anchor, while Savage's direction and Wan's production pedigree supply the horror credentials that drive opening-weekend turnout. The combination has become something of a template for studios looking to compete without the marketing costs of a tentpole franchise.
The bigger picture for exhibitors is that horror continues to function as a dependable theatrical draw at a time when many other genres struggle to lure audiences away from streaming. The genre's 2026 winning streak — from «Obsession» through «Backrooms» and «Resident Evil» to «Other Mommy» — has given multiplexes a steady supply of event titles heading into the fall season.
Whether «Other Mommy» can hold its audience beyond opening weekend will depend on word of mouth among horror fans, who often turn out early and then move on quickly. But for now, the film has claimed the top spot and given the genre another strong entry in what has become its most dominant year in recent memory.
