**Other Mommy** benefits from strong pre-Halloween horror demand and Jessica Chastain’s proven genre draw, pushing trader consensus toward a $30M-plus domestic debut despite conservative industry tracking in the low $20Ms. Blumhouse and Atomic Monster’s original R-rated supernatural thriller, directed by Rob Savage and based on Josh Malerman’s novel, has gained momentum from robust trailer views and favorable audience demographics ahead of its October 9 wide release. With limited competition from the weaker-tracking *The Social Reckoning*, the film’s 3,200-theater rollout and potential for premium large-format play position it to outperform modest forecasts if early reviews or word-of-mouth prove positive. No critic scores are available yet, leaving room for late shifts in sentiment before the weekend numbers lock.
