Brittany Snow has joined the cast of The Housemaid's Secret, Lionsgate's sequel to its upcoming adaptation of Freida McFadden's bestselling thriller The Housemaid, according to The Hollywood Reporter. Snow will play a character named Marybeth.

The sequel brings back Sydney Sweeney as its lead, with Michele Morrone reprising his role as Enzo from the first film. Paul Feig, who directed the initial installment, returns to the helm. New additions to the cast alongside Snow include Kirsten Dunst and Paul Anthony Kelly.

Rebecca Sonnenshine, who adapted the first Housemaid book for the screen, wrote the script for The Housemaid's Secret, which is based on the second novel in McFadden's Housemaid series. Production is due to begin later in 2026, and Lionsgate has set a release date of 17 December 2027.

The producing team is a familiar one. Todd Lieberman of Hidden Pictures, Laura Fischer and Paul Feig of Pretty Dangerous Pictures, and Sydney Sweeney through her Honey Trap banner all produce. Carly Elter returns as executive producer, with Alex Young of Hidden Pictures also executive producing. Honey Trap's Kaylee McGregor co-produces. Chelsea Kujawa and Maria Ascanio are overseeing the project for Lionsgate.

For context, the first film — The Housemaid — stars Sweeney alongside Amanda Seyfried and is scheduled to reach Netflix on 25 December 2025, as The Hollywood Reporter noted in March 2025. Variety had confirmed Seyfried's casting and the Christmas 2025 release in December 2024.

The sequel's December 2027 corridor places it squarely in the holiday window that studios prize for crowd-pleasing, book-adjacent titles. Snow, whose credits stretch from the Pitch Perfect franchise to the 2022 psychological thriller X, adds another recognisable face to a cast already headlined by Sweeney and now bolstered by Dunst — a combination that gives Lionsgate real star density as it builds out a franchise from McFadden's page-turner series.

What is striking here is the speed of the chain. The first film has not even reached streaming audiences yet, and its sequel is already cast, scripted, dated, and preparing to shoot. Lionsgate is treating McFadden's Housemaid books the way studios treat any proven IP — as a pipeline to be loaded well in advance, not a single film to be tested before a second is greenlit.
