**Recent tracking for the Blumhouse-produced supernatural horror film positions "Other Mommy" for a mid-teens to mid-20s million dollar domestic opening weekend, with October genre precedents like Smile 2 and Black Phone 2 providing the main benchmarks.** Jessica Chastain's dual role, James Wan's producing involvement, and Rob Savage's direction from the Josh Malerman novel have generated solid trailer engagement, yet the spread of market-implied probabilities across the sub-$21M through $30M+ ranges highlights ongoing uncertainty. Traders appear to weigh the film's limited built-in IP against Blumhouse's consistent horror output and the relatively light competition on its October 9 date, including The Social Reckoning. Final presales, exit polling from advance screenings, and any late marketing spikes will likely determine whether the result lands toward the lower or upper end of expectations.
