Lionsgate has officially slated The Housemaid’s Secret for a wide theatrical release on December 17, 2027. The psychological thriller sequel sees Sydney Sweeney reprising her role as Millie, joined by new lead Kirsten Dunst.

A New Household and a Locked Door

Adapted from Freida McFadden’s best-selling second novel, the sequel follows Millie as she takes on a new job in another wealthy household, only to uncover something deeply unsettling hidden behind a locked door.

Key production details for the upcoming installment include:

• Sydney Sweeney returning as the lead protagonist, Millie.

• Kirsten Dunst joining the cast in a major leading role.

• Michele Morrone reprising his role as Enzo.

• Paul Feig returning to direct from a screenplay by Rebecca Sonnenshine.

Building on Global Box Office Success

Following the runaway success of the original The Housemaid—which grossed nearly $400 million worldwide—Lionsgate fast-tracked the sequel, with principal photography scheduled to begin in late 2026.

Contrary to earlier rumors, Amanda Seyfried has not been confirmed to return as a main cast member, and the project remains a traditional theatrical release rather than a Netflix feature. A new home, another dangerous family, and even darker secrets await when The Housemaid’s Secret hits theaters in December 2027.
