Jessica Chastain’s Other Mommy release date is Friday, and the supernatural horror film enters theaters as part of October Halloween programming. For readers tracking what lands now, it is one of 12 new spooky movies and shows being used to sell the season.
Friday is the only timing marker given for the theatrical launch, which leaves the calendar date itself unstated even as the movie’s arrival is fixed to the weekend slot. That is the practical detail here: the film is moving from the preview stage to a public theatrical release, and audiences planning a Halloween-season watch now have the widest possible window to catch it opening day.
Jessica Chastain in Other Mommy
Jessica Chastain plays both the girl’s mother and the entity haunting the child, a dual role that turns the casting into part of the film’s premise rather than a standard genre paycheck. Other Mommy centers on a young girl who starts seeing a sinister woman hiding in the shadows of her home and calling her “Other Mommy.”
The setup makes the release matter beyond a title drop. A supernatural horror film built around one performer in two roles asks viewers to track identity as the source of fear, which is a cleaner hook than simply labeling it another seasonal scare. It also gives the movie a specific selling point inside an October slate that is crowded with new spooky releases.
October Halloween slate
12 new spooky movies and shows are part of the October Halloween lineup, and Other Mommy sits inside that group rather than outside it. The month’s broader menu also includes fresh takes on Carrie and Friday the 13th, which means the film is competing for attention in a field already built around familiar horror names and seasonal browsing habits.
That context is the complication for a release landing on Friday: the movie is not opening in isolation, but in a packed stretch where viewers can choose between returning properties and new titles. In that kind of market, the most useful detail is not hype but timing, and Friday is now the key ticket-buying day for anyone who wants Other Mommy first.
What Friday delivers
Friday gives the film its first real test with audiences, and the next step is simple: theaters will decide whether Jessica Chastain’s dual-role pitch and the child-at-home premise are enough to separate Other Mommy from the rest of the October slate. For now, the answer readers need is straightforward — the movie arrives this Friday, and that is the date that matters when the Halloween schedule starts to fill up.
