The unexpected success of the psychological thriller secures a sequel that will continue Millie Calloway’s story, with Sydney Sweeney set to reprise her role.
The phenomenon of The Housemaid is far from over. Less than a month after its theatrical release, Lionsgate has officially confirmed the development of a sequel to the psychological thriller, with Sydney Sweeney returning as Millie Calloway. The new film will be titled ‘The Housemaid’s Secret’ and will adapt the second novel in The Housemaid, the bestselling trilogy by Freida McFadden.
The decision follows a striking box office performance. Since its release on 19 December, the film has grossed $133 million worldwide in just over two weeks, positioning itself as one of the year’s most unexpected commercial hits. This momentum fast-tracked the studio’s greenlight, although sources indicate the sequel had already been in development for several months.
Alongside Sydney Sweeney, Michele Morrone is set to return, as is director Paul Feig, ensuring creative continuity and preserving the unsettling psychological tone that defined the original film. Production is scheduled to begin later this year.
The first instalment followed Millie Calloway, a young woman with a criminal past who takes a live-in housekeeping job with the wealthy Winchester family. What initially appears to be a chance at redemption quickly descends into a claustrophobic nightmare of manipulation, control and buried secrets. As the story unfolds, it becomes clear that the true danger lies not outside the house, but within it.
With ‘The Housemaid’s Secret’, the narrative moves deeper into Millie’s psyche, expanding her backstory and confronting the consequences of her past choices. The adaptation of the second book promises heightened emotional stakes and an even more unstable moral terrain for audiences.
For Sydney Sweeney, the sequel further cements her status as one of the most in-demand leads in contemporary commercial cinema, capable of anchoring high-impact releases beyond television drama. For Lionsgate, the follow-up confirms that psychological thrillers remain a powerful box office force when sharp storytelling, complex characters and confident execution converge.
