Content overview: “Jessica Chastain's 'Other Mommy' Scares Up $3.6M in Previews, Eyes $22M-$28M Horror Debut”. Universal and Blumhouse-Atomic Monster's 'Other Mommy,' starring Jessica Chastain, earned $3.6 million in Thursday previews from 2,850 domestic screens. The horror film is projected to open between $22 million and $28 million this weekend, continuing the genre's hot streak after 2026 hits like 'Obsession' and 'Backrooms.' The strong preview number signals robust audience interest in Chastain's return to horror, a genre where she has previously drawn crowds. With Universal's wide release strategy and the production house's track record for low-budget, high-return scares, 'Other Mommy' could become another profitable entry in the Blumhouse-Atomic Monster pipeline.
For the industry, a solid opening would reinforce horror's reliability as a box office driver, especially for original concepts not based on existing IP. Chastain's star power combined with the film's unsettling premise appears to be resonating with moviegoers seeking communal frights.
