Jessica Chastain Stars in Blumhouse Horror 'Other Mommy' Trailer

Universal Pictures and Blumhouse released the official trailer for their psychological horror film 'Other Mommy' on an unspecified date, showcasing Academy Award winner Jessica Chastain in a dual role. Chastain portrays both a protective mother and her malevolent supernatural doppelgänger. The film is directed by Rob Savage, known for 'Host' and 'The Boogeyman', and adapted from Josh Malerman's novel 'Incidents Around the House' by Succession writer Nathan Elston.

James Wan, under the Blumhouse Atomic Monster banner, is producing the feature. The narrative focuses on eight-year-old Bela, played by Arabella Olivia Clark, who is stalked by a terrifying entity from her closet that eerily resembles her mother. The trailer highlights Chastain's return to the horror genre, following her roles in 'Mama' and 'It Chapter Two'.

Jessica Chastain's co-stars include Jay Duplass as Bela's father. The supporting cast features Dichen Lachman, Arian Moayed, and Karen Allen. The film promises a blend of domestic vulnerability and supernatural dread. 'Other Mommy' is scheduled for theatrical release on October 9, 2026, distributed by Universal Pictures.
