Brittany Snow is set to star in Lionsgate’s upcoming thriller sequel “The Housemaid’s Secret,” joining a cast that already includes Sydney Sweeney, Kirsten Dunst, and Paul Anthony Kelly. The film is positioned as a follow-up to Lionsgate’s 2025 surprise box-office hit “The Housemaid.” Based on Freida McFadden’s bestselling novel, “The Housemaid’s Secret” continues the story with Sweeney’s character, Millie, working as a live-in maid. Variety and the other outlets report that Snow will play Marybeth, with Deadline tying the production to Todd Lieberman’s Hidden Pictures and additional partners, and noting Snow’s recent work with Lionsgate on the TV series “The Hunting Wives.”

Paul Feig is directing the sequel. The announcements across outlets focus on Snow’s casting, the ensemble of returning/new principal stars, the project’s connection to McFadden’s novel, and the film’s status as the follow-up to “The Housemaid.” No release date or additional plot specifics beyond the continuation through Millie’s maid role are provided in the excerpts.
