Sydney Sweeney has begun filming The Housemaid’s Secret, returning as Millie Calloway in the Lionsgate thriller sequel based on Freida McFadden’s follow-up novel.
The production update was announced on October 15, 2026, through the film’s official social-media channels, which shared a behind-the-scenes video confirming that cameras were rolling.
The sequel reunites Sweeney with director Paul Feig and co-star Michele Morrone, who returns as Enzo.
Kirsten Dunst, Brittany Snow, Paul Anthony Kelly and Stephen Kalyn are among the new additions to the cast.

Sydney Sweeney returns as Millie
In the first film, Sweeney played Millie, a young woman with a troubled past who takes a live-in housekeeping job with a wealthy family.
The sequel moves the character into a new household and a new mystery.
The official premise says Millie accepts a job caring for a woman she is never allowed to see, only to discover that the secrets behind a locked door may be more dangerous than anything she has previously faced.
The story is adapted from McFadden’s novel The Housemaid’s Secret, the second book in the author’s best-selling series.
Lionsgate announced in January that the sequel was being developed after the commercial success of The Housemaid, with Sweeney attached as both a returning star and executive producer.
Filming is taking place in New Jersey
Production activity has been reported in northern New Jersey, including Hoboken, where filming affected local streets and businesses in October.
Hoboken officials said the production paid roughly US$22,000 for permits and temporary parking restrictions connected with the shoot.
Local filming reports also identified Sweeney and other cast members working at locations around the city.
The New Jersey setting continues the production connection established by the first film, which also used locations in the state.

A new project during a busy year for Sweeney
The sequel gives Sweeney another major film role as her profile continues to expand across theatrical projects, television and commercial partnerships.
Her recent work has also drawn attention outside traditional film coverage, including criticism of a provocative sports-prediction advertisement.
CTCNews.ca previously reported on backlash from women athletes over that campaign.
Unlike that advertising controversy, The Housemaid’s Secret represents a formal studio production milestone, with Sweeney returning to a character connected to one of her recent box-office successes.
When will The Housemaid’s Secret be released?
The sequel is expected to arrive in theatres in 2027, although Lionsgate has not yet published a complete marketing schedule.
Further details, including a trailer and confirmed international release dates, are expected as production continues.
For now, the latest confirmed development is that filming is underway, with Sweeney back in the lead role and Dunst joining the cast for the next chapter of the thriller franchise.
