Universal drops Trailer #2 for Rob Savage’s Other Mommy
What happened
FirstShowing, dated September 15, 2026, posts Universal Pictures’ second full trailer for Rob Savage’s horror film Other Mommy. The film is scheduled for U.S. theaters starting October 9, 2026. Coverage frames the story around Bela, an 8-year-old who confronts a sinister closet entity that looks exactly like her mother — a presence she names “Other Mommy.” Oscar winner Jessica Chastain is reported in dual roles as Bela’s mother and as the entity; Jay Duplass plays the father, and Arabella Olivia Clark plays Bela. Culture packages here recap the dated trailer drop, the studio, the release date, the dual-role hook, and the source novel — not a spoiler dump and not a likeness gallery.
The feature is adapted from Josh Malerman’s novel Incidents Around the House, with a screenplay by Nathan Elston; Rob Savage (Host, Dashcam, The Boogeyman) directs. Producers listed in the FirstShowing write-up include James Wan, Macdara Kelleher, and Judson Scott, under the Blumhouse Atomic Monster banner tied to Wan. Cartoon figures only — never celebrity likenesses and never photoreal portraits of living actors. Prose may name reported roles as printed without claiming the cartoon panels look like anyone. Bright closet-purple and Universal night blue. White gutters. The FirstShowing URL is the receipt. Skip politics-adjacent casting chatter. A October theatrical Savage trailer with a firm Malerman lineage is a clean Culture slot for this batch.
Trailer filings stay short on plot and long on logistics. Readers get FirstShowing’s Sept. 15 post, Universal Trailer #2, Rob Savage, the Oct. 9 date, Chastain’s dual-role entity-from-the-closet hook, Malerman’s Incidents Around the House, and the Blumhouse Atomic Monster / James Wan producing credit — the board that matters when the clapper snaps shut.
Why it matters
The strip is the closet-door glow, the dual-role mother/entity stand-ins, the ball-pit trailer motif, and the Oct 9 Coming Soon board. Color on the eerie glow and the Universal stub. White gutters. No celebrity portraits. Readers get the Savage / Universal / Malerman package, the dual-role closet entity hook, and the dated Trailer #2 drop without wandering into politics.
Conclusion
FirstShowing’s Sept. 15 Universal Trailer #2 for Rob Savage’s Other Mommy flags an Oct. 9 theatrical release, Jessica Chastain in dual roles as mother and closet entity, and an adaptation of Josh Malerman’s Incidents Around the House from Blumhouse Atomic Monster and producer James Wan. Cartoon stand-ins only. Source: https://www.firstshowing.net/2026/super-creepy-jessica-chastain-in-horror-other-mommy-full-trailer-2/
