Jessica Chastain’s dual role puts the child’s mother and the entity inside the same visual identity.
Other Mommy places a familiar face on an unfamiliar presence. Bela forms a relationship with an entity inside her home that resembles her mother, and Jessica Chastain plays both the parent and the entity’s manifestation. NBCUniversal’s character, adaptation, and cast details.
That casting gives the premise a concrete form: the person Bela recognizes and the presence threatening her family look alike. Universal’s synopsis describes the entity as actively manipulative, moving beyond an explanation that it is simply something the child imagines.
Arabella Olivia Clark plays Bela, with Jay Duplass as her father, Daddo. Rob Savage directs Nathan Elston’s adaptation of Josh Malerman’s novel Incidents Around the House. James Wan produces.
Universal lists the digital edition for November 10, 2026, followed by physical editions on December 29. The home release includes deleted and alternate scenes. Its theatrical story remains organized around Bela’s relationship with the presence: a threat that enters family life wearing the mother’s likeness. Universal’s home-edition specifications and dates.
