Who is Other Mommy, and will you let her into your heart? OTHER MOMMY elevates the terror at home for its debut exclusively on digital platforms beginning November 10, 2026, and on 4K and Blu-ray™ on December 29, 2026, from Universal Pictures Home Entertainment. Director Rob Savage pushes heightened horror into chilling new territory with the psychologically thrilling film OTHER MOMMY. Alongside Jessica Chastain’s terrifying performance, the film also features intense performances from its ensemble cast, including Dichen Lachman (Severance), Sean Kaufman (The Summer I Turned Pretty), and Jay Duplass.

Academy Award® winner Jessica Chastain stars in a terrifying trip into the darkening world of a young girl, Bela, who forms a relationship with a disturbing entity in her home who looks uncannily like her own mother. “Other Mommy” proves to be more than a mere figment of the girl’s imagination as she becomes a sinister, manipulative presence determined to tear apart Bela’s family.
