Recent tracking updates have lifted expectations for Universal’s Blumhouse horror *Other Mommy*, with Box Office Theory forecasting a $25–35 million domestic debut ahead of its October 9 release. Jessica Chastain’s dual role, James Wan’s producing involvement, and the October horror window provide solid momentum, yet the original IP—adapted from Josh Malerman’s novel—lacks the built-in fanbase that drove larger openings for franchise titles. Traders appear split on whether strong presales and genre timing can push the film toward the upper end of projections or if typical Blumhouse variability and competition will cap results near $25–30 million, reflecting the market’s tight distribution across the 30 million-plus brackets.
