Other Mommy Filming Locations

Rob Savage’s Other Mommy turns an ordinary family home into the center of a deeply unsettling supernatural story. Jessica Chastain plays Ursula as well as the entity that takes on her appearance, while Arabella Olivia Clark stars as eight-year-old Bela, the child who begins communicating with the figure she calls Other Mommy. Jay Duplass plays Bela’s father, Russ, with Dichen Lachman, Arian Moayed and Karen Allen among the supporting cast. The Universal and Blumhouse Atomic Monster film is adapted from Josh Malerman’s 2024 novel Incidents Around the House and opens in US theaters on October 9, 2026.

Although the story is rooted in an American family setting, the production was made across Ireland. Dublin served as the main base, while production records also identify Wicklow as a filming area. The movie shot in 2025 under the working title Grandma’s House, long before Universal settled on Other Mommy as the final release title.

Dublin was the main base for Other Mommy

Principal photography was centered in Dublin, where production was scheduled from May 12 through July 9, 2025. The Irish capital appears consistently in production records for Grandma’s House, the title used while the movie was filming. Screen Global Production later reported that the Ireland shoot had wrapped by July 2025, confirming that the production completed its work in the country that summer.

Dublin was an especially useful base for a story that depends less on sweeping landscapes than on the increasingly uncomfortable feeling of being trapped inside familiar domestic spaces. Other Mommy spends much of its time around Bela and her family, with the house becoming inseparable from the presence following them. The city and its surrounding residential areas gave the filmmakers access to the kind of everyday architecture needed to make that world feel ordinary before the supernatural elements take over.

What has not been publicly established is the exact address of Bela’s house. Some online location summaries describe a real Dublin residential property as the family home, but the reliable production material available so far does not identify a specific street or house. Until the production, property owner or a local filming notice confirms one, it is better not to attach an unverified address to the movie.

Josh Malerman spent several days on the Dublin set

The Dublin connection is also confirmed by the author whose novel inspired the film. Malerman told The Hollywood Reporter that he, his wife Allison and his manager traveled to Dublin and spent four or five days on set while Other Mommy was being made. Unlike Bird Box, which had been optioned before his first novel was even published, Malerman was more involved with this adaptation as an executive producer and was kept informed throughout the process.

His visit offers useful confirmation that Dublin was not merely an administrative production address. It was where the main creative work was happening. Malerman described Savage as a filmmaker with a distinct visual approach and said seeing the finished adaptation convinced him that the story had landed with a director who had made it his own.

That matters for a movie such as Other Mommy because the source novel is unusually concentrated around the home. Malerman himself has described Incidents Around the House as a largely single-setting story, which placed extra pressure on the filmmakers to make the central domestic environment visually interesting without losing the sense that it is still just a family’s house.

Wicklow was the production’s second Irish location

Production records also list Wicklow alongside Dublin. The listing for Grandma’s House names both places as filming locations, confirming that the production moved beyond the capital during its roughly two-month shoot.

Publicly available material does not yet provide a reliable list of individual Wicklow addresses or buildings used in the finished movie. That makes it difficult to say whether a particular road, property or countryside setting can be matched confidently to a scene. Wicklow should therefore be treated as a confirmed production area rather than a collection of specific tourist stops.

The location still makes sense for the film’s visual needs. Wicklow lies directly south of Dublin and gives productions easy access to quieter towns, residential areas and rural landscapes without moving too far from a Dublin production base. That contrast can be particularly useful for a movie that begins with a recognizable family environment but gradually makes the world around Bela feel more isolated.

For viewers hoping to visit exact Other Mommy sites, Dublin currently offers the strongest confirmed connection, while Wicklow remains a broader regional filming location until more detailed production records or local reports emerge.

Other Mommy was filmed under the title Grandma’s House

Anyone looking through Irish production records from 2025 may not find Other Mommy immediately. The film was shooting under the working title Grandma’s House, with preparation beginning in March and principal photography scheduled for May through July. ProductionList identifies Rob Savage as director, Nathan Elston as screenwriter, and James Wan, Michael Clear, Judson Scott and Irish producer Macdara Kelleher among the producing team.

The working title helps explain why contemporary filming notices and production databases may not use the name audiences now know. The project was initially announced as an adaptation of Incidents Around the House before being retitled Other Mommy during production and post-production. Crew records likewise connect the film to Ireland while listing Atomic Monster, Blumhouse and Wild Atlantic Pictures among the companies involved in the shoot.

That Irish production connection was substantial rather than incidental. Wild Atlantic Pictures helped anchor the international project locally, while the crew included Ireland-based production and art department workers alongside Savage’s returning collaborators.

Was Other Mommy filmed in Michigan?

No confirmed production evidence places the movie’s principal shoot in Michigan. The screen adaptation was made in Ireland, with Dublin and Wicklow providing the real locations behind Bela’s world.

That distinction is useful because Malerman is a Michigan-based writer and the source novel is strongly associated with an American suburban setting. The movie preserves that familiar domestic atmosphere without requiring the production to shoot in the United States.

Ireland has long been able to double for locations well beyond its own borders, and Other Mommy uses that flexibility in a particularly contained way. The goal is not to make Dublin or Wicklow recognizable on screen. It is to create a house and neighborhood that feel normal enough for the supernatural intrusion to become more disturbing.

When was Other Mommy filmed?

The strongest production record gives a scheduled principal photography window of May 12 through July 9, 2025, with preparation beginning on March 26. IMDb lists a slightly broader April 24 to July 15 filming period, most likely reflecting additional production activity around the main shoot.

By late July 2025, Screen Global Production reported that the Ireland shoot had wrapped. The movie then spent more than a year in post-production before its October 2026 theatrical release.

The finished film ultimately hides much of that Irish geography behind Bela’s increasingly claustrophobic family world. Dublin provided the production’s main foundation, Wicklow expanded the available locations, and the house at the center of the story was shaped to feel less like an identifiable destination than a place that could belong to almost any family. For Other Mommy, that anonymity is part of what makes the setting work.
