The twists keep coming for Sydney Sweeney’s unforgettable character Millie Calloway.
Lionsgate just announced that The Housemaid’s Secret, the sequel to 2025’s box office hit The Housemaid, will begin filming this year.
Sweeney returns to play the complex housemaid who can’t seem to escape dangerous employers, and director Paul Feig is back behind the camera.
Fans of Freida McFadden’s addictive thriller novels have every reason to celebrate—another dark mystery is coming to screens.
Sydney Sweeney Returns as Millie Calloway
The announcement confirms Sweeney will reprise her role as Millie, the formerly incarcerated woman whose new job opportunities repeatedly thrust her into perilous situations. Michele Morrone also returns as Enzo, the groundskeeper who appeared in the first film.
Rebecca Sonnenshine, who adapted the original screenplay, will write The Housemaid’s Secret based on McFadden’s 2023 novel. Paul Feig, known for his work on Bridesmaids and A Simple Favor, returns to direct after helming the first installment.
What Happened in The Housemaid
The Housemaid premiered in theaters on December 19, 2025, and quickly became a box office success. Based on McFadden’s 2022 novel, the film introduced audiences to Millie Calloway, who secures employment as a live-in housekeeper for the wealthy Winchester family.
Andrew Winchester, played by Brandon Sklenar, appears as a devoted father. His wife Nina, portrayed by Amanda Seyfried, treats Millie with cruelty and displays erratic behavior that raises serious concerns about Millie’s safety.
But nothing in thriller territory stays simple for long.
As the story unfolds, Millie discovers shocking secrets about the Winchester household—secrets that reveal the mansion might be its own kind of prison. The film’s twist-heavy narrative kept audiences guessing until the final moments.
What to Expect from The Housemaid’s Secret
The sequel picks up Millie’s story as she takes another position with a wealthy employer. In McFadden’s novel, Millie works for a well-off woman who appears to be suffering abuse at the hands of her husband.
Attempting to help her new boss, Millie becomes entangled in an increasingly complex web of lies and deception. Given McFadden’s reputation for jaw-dropping plot twists, viewers can expect multiple revelations that upend everything they think they know.
The Housemaid’s Secret is the second book in McFadden’s three-novel series about Millie. Each installment follows her into a new mysterious—and dangerous—situation.
Freida McFadden’s Thriller Empire
McFadden, a practicing physician who writes under a pen name, has become one of thriller fiction’s most prolific voices. Her ability to craft page-turning mysteries with shocking endings has made her novels irresistible to Hollywood.
Multiple McFadden adaptations are currently in development:
- The Surrogate Mother (based on her 2018 novel) is being developed by Sony for theatrical release
- The Teacher (based on the 2024 novel) is in production at Apple Original Films
- The Tenant (her 2025 thriller) will be adapted by Amazon
- Dear Debbie (releasing later this month) is being developed as a television series for Amazon
The Housemaid series includes three novels total. Beyond The Housemaid (2022) and The Housemaid’s Secret (2023), McFadden published The Housemaid Is Watching in 2024. She also wrote The Housemaid’s Wedding, a short story released in 2025.
Why The Housemaid Resonated with Audiences
The first film’s success stems from its exploration of power dynamics, class differences, and the masks people wear. Millie’s status as a formerly incarcerated woman trying to rebuild her life adds layers of vulnerability and determination to her character.
Sweeney’s performance captured Millie’s intelligence and resourcefulness while navigating environments designed to keep her powerless. The film examined how wealth can create its own forms of imprisonment—gilded cages that trap everyone inside.
McFadden’s novels have attracted massive readership precisely because they flip familiar domestic thriller tropes on their heads. Just when readers think they understand what’s happening, she pulls the rug out completely.
Production Timeline and Release Expectations
With filming scheduled to begin this year, The Housemaid’s Secret could potentially reach theaters in 2026 or early 2027, depending on post-production schedules. Lionsgate hasn’t announced an official release date yet.
The quick turnaround between the first film’s release and the sequel’s production announcement signals strong confidence in the franchise’s commercial viability. Given the original’s box office performance and McFadden’s devoted fanbase, that confidence appears well-founded.
Fans who’ve read ahead in the series already know Millie’s journey doesn’t end with the second book. Whether Lionsgate will eventually adapt The Housemaid Is Watching likely depends on how The Housemaid’s Secret performs.
For now, audiences can look forward to watching Millie navigate another treacherous household where nothing—and no one—is quite what they seem. Sweeney has proven she can carry suspenseful material, and Feig’s direction should maintain the stylish tension that made the first film so compelling.
McFadden’s thrillers thrive on keeping readers guessing until the very last page, and translating that experience to screen requires careful pacing and misdirection. If The Housemaid’s Secret delivers even half the surprises of its source material, audiences are in for another wild ride through the dark corridors of wealth, secrets, and survival.
