Other Mommy opens to $27.5M despite 18% critics

The horror hit of the weekend is a case study in selling a feeling rather than a film. Other Mommy, Blumhouse-Atomic Monster’s adaptation of Josh Malerman’s 2024 novel Incidents Around the House, took the top spot with an estimated $27.5 million domestic opening. Add $17.7 million from overseas and the worldwide tally stands at $45.2 million.

Those are strong numbers for a movie that opened cold with critics: 18% on Rotten Tomatoes, a 2.3 average on Letterboxd, and a D+ CinemaScore, the lowest since Megalopolis in September 2024.

The trailer did the selling

Universal attached the first trailer to July screenings of Christopher Nolan’s The Odyssey, putting Jessica Chastain’s contorting monster in front of audiences who had not signed up for a horror pitch. The trailer became its own meme, and Boxoffice Pro tracking moved up after the placement, with forecasts briefly climbing as high as $35 million before settling at $17 million to $22 million. The film beat that range.

The campaign then kept the imagery simple: an Oscar winner, an elastic body, an expression you remember. It did not need to explain the film’s supernatural mythology or ask audiences to know the source novel. The less it said, the more it sold.

Why next weekend is the real test

The question is what happens now that the promise has run into the product. Blumhouse’s recent comparisons show the spread:

  • Night Swim: $11.8M opening, 61% second-weekend drop, over $40M global.
  • Imaginary: $9.9M opening, 44% drop, over $40M global.
  • M3GAN: $30.4M opening, 40% drop, over $180M global, 93% Rotten Tomatoes.

Other Mommy has a reported $19 million production budget before marketing, so it is already in a healthy position. It is also Blumhouse-Atomic Monster’s biggest domestic opening of 2026 so far, ahead of Obsession and the latest Insidious.

But the D+ CinemaScore matters because it is the best predictor we have of word of mouth. Audience reaction is already turning the gap into a meme. As one Letterboxd user put it, “the surprise drop of the first trailer was way scarier and better than the actual movie.”

Scheduling press screenings less than 24 hours before release kept reviews out of the opening conversation, but it also leaves the film exposed now that audience reaction is public. A great trailer buys one weekend; the second weekend tells you whether the audience got what the marketing promised.

The trust ledger

Blumhouse has built its brand on low-cost, high-concept horror, and that goodwill is real. The risk in a trailer-led event is not the opening; it is the next ticket. If every campaign promises a M3GAN but delivers a Night Swim, the audience starts to discount the next intriguing one-sheet. A viral trailer can buy attention once. The second weekend will show whether Other Mommy bought repeat interest or just borrowed it.
