The horror film Other Mommy, starring Jessica Chastain, opened to strong box office results despite negative reviews from critics and audiences. The film delivered an impressive debut in the United States, topping the domestic box office in its opening weekend and generating additional revenue from international markets.
The film’s commercial performance stands in contrast to its poor critical reception, making its opening weekend particularly noteworthy for a mid-budget horror production.
Other Mommy Tops the U.S. Box Office

The film performed particularly well in the North American market. Released in the United States on October 9, Other Mommy earned $27.5 million during its opening weekend, claiming the top spot at the domestic box office.
The movie opened in 3,365 theaters, surpassing initial projections that had estimated a debut in the $20 million range. International markets also contributed to its strong performance, generating approximately $17.7 million in additional ticket sales.
As a result, the film grossed approximately $45.2 million worldwide during its opening weekend. With an estimated production budget of $19 million, the debut represents a promising commercial start for a mid-budget horror film. However, marketing expenses and the share of ticket sales retained by theaters must also be considered when assessing the movie’s overall profitability.
Jessica Chastain’s Horror Film Divides Critics and Audiences

Despite its strong box office performance, Other Mommy has struggled with critics and moviegoers. The film received an approximately 16% critics’ score on Rotten Tomatoes following its release and earned a D+ CinemaScore grade, based on surveys of moviegoers after theatrical screenings.
The contrast between the film’s box office success and its negative reception raises questions about whether it can maintain its momentum in the coming weeks. For horror movies, strong opening-weekend numbers can help attract audiences, but word of mouth also plays an important role in sustaining ticket sales.
Even so, the opening demonstrates how audience interest in the horror genre and the star power of Jessica Chastain can help drive a theatrical release, even when critical and audience reactions are less favorable.
