Other Mommy Drops New Trailer and Poster
Universal Pictures has released the new trailer and poster for Other Mommy, the anticipated supernatural psychological horror film opening in theaters on October 9, 2026. Tickets for the film, which has been rated R for some bloody violence and language, are now available.
From producer James Wan, one of the most influential architects of modern horror, and Blumhouse Atomic Monster, the studio behind Backrooms and Obsession, comes a terrifying trip from breakout genre director Rob Savage.
The film centers on the darkening world of a young girl, Bela, who forms a relationship with a sinister entity in her home who looks uncannily like her own mother.
Academy Award winner Jessica Chastain (It Chapter Two, The Eyes of Tammy Faye) stars in dual roles as Bela’s mother and as “Other Mommy,” a manifestation of the entity. Jay Duplass (Transparent, Industry) plays Daddo, Bela’s father, and Arabella Olivia Clark (The Housemaid, The Hand that Rocks the Cradle) plays Bela.
The supporting cast includes Actor Award nominee Dichen Lachman (Severance), Emmy and Tony Award nominee Arian Moayed (Succession), and screen legend Karen Allen (Indiana Jones films).
Other Mommy is directed by Rob Savage (Host, The Boogeyman) from a screenplay by WGA Award winner Nathan Elston, writer for the Emmy-winning sensation Succession.
The movie is based on the New York Times bestselling novel Incidents Around the House by Josh Malerman (Bird Box).
The film is produced by James Wan, p.g.a. (Saw, Insidious, and Conjuring franchises) of Blumhouse Atomic Monster, and is executive produced by Michael Clear, Judson Scott, Rob Savage, Josh Malerman, and Ryan Lewis.
