The Housemaid's Secret

Millie Takes Another Dangerous Housekeeping Job

The Housemaid's Secret sends Sydney Sweeney's Millie Calloway into another wealthy home where the rules do not add up. She is hired to help a woman she is not allowed to see, and the locked door between them quickly suggests that this job carries darker secrets than Millie's employers are admitting.

Kirsten Dunst Enters the Upstairs Mystery

Kirsten Dunst joins Sweeney in the sequel, with Brittany Snow also among the announced cast. The new household gives Millie another polished surface to investigate, but her own complicated history means she is never merely an innocent visitor stumbling into someone else's trouble.

The First Film's Team Returns

Paul Feig is back to direct, while Rebecca Sonnenshine returns to adapt Freida McFadden's bestselling second novel. Producers include Todd Lieberman, Feig and Laura Fischer through Pretty Dangerous Pictures, and Sweeney through Fifty-Fifty Films, keeping much of the creative group behind the first movie in place.

A Thriller Stakes Out the Holiday Box Office

Lionsgate has set a wide theatrical release for December 17, 2027. The date gives the sequel a major holiday frame following the first film's nearly $400 million worldwide run. More importantly, it gives Millie a second chance to do what made the original story click: walk into a locked-down home, notice what everyone else avoids, and decide which secrets deserve to stay buried.
