Sydney Sweeney’s The Housemaid has surged to the top of HBO Max’s movie charts in October 2026, becoming the streamer’s most-watched film this month. The R-rated psychological thriller, which first hit theaters in December 2025, earned $400.5 million worldwide against a $35 million budget — proof of its box office strength. Now, after making its streaming debut on Starz in April 2026, it moved to HBO Max on October 9 and quickly climbed to number one. According to FlixPatrol data, it claimed the top spot on October 11 and remained there as of October 12, overtaking both Backrooms, which had held the position for weeks, and Evil Dead Burn, which launched on October 2. The film’s resurgence is not just about numbers, it’s about momentum. Fans are revisiting the story of Millie Calloway (Sweeney), a former inmate who takes a job as a live-in maid for the wealthy Winchester family. Her relationship with Nina Winchester (Amanda Seyfried) and her husband Andrew (Brandon Sklenar) unravels into something far more dangerous than domestic service. The adaptation, written by Rebecca Sonnenshine and directed by Paul Feig, was based on Freida McFadden’s 2022 novel of the same name. Critics praised the film’s tension and performances, especially Seyfried’s portrayal of a woman whose control masks deeper instability. That performance may now be at risk: the sequel, titled The Housemaid’s Secret, is set for release in December 2027, but it does not feature Nina Winchester. Whether Amanda Seyfried will return remains unconfirmed. Lionsgate has not announced casting plans for the follow-up, though the studio is clearly banking on the original’s staying power. For now, the success on HBO Max suggests audiences still crave the series’ blend of suspense, intimacy, and betrayal. The platform’s viewership spike confirms that even after a theatrical run and a prior streaming stint, the story isn’t done yet.
