Your mommy won’t save you. Other Mommy only in theatres October 9.

Can I go inside your heart?

From James Wan, one of the most influential architects of modern horror behind the Saw, Insidious and The Conjuring franchises—and Rob Savage, the director of bold genre films Host and The Boogeyman, comes a terrifying trip into 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 a dual role 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 impressive 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).

From Blumhouse Atomic Monster, Other Mommy is directed by Rob Savage from a screenplay by WGA award winner Nathan Elston, writer for the Emmy-winning sensation Succession, 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., and is executive produced by Michael Clear, Judson Scott, Rob Savage, Josh Malerman and Ryan Lewis.
