Stephen Kalyn Joins Sydney Sweeney in Lionsgate's The Housemaid's Secret Sequel

Kirsten Dunst will portray Mrs. Garrick and Paul Anthony Kelly will play her husband Douglas Garrick in The Housemaid’s Secret.
The production team for The Housemaid’s Secret includes Carly Elter returning as executive producer, with Alex Young of Hidden Pictures also executive producing, Kaylee McGregor of Honey Trap co-producing, and Lionsgate’s Chelsea Kujawa and Maria Ascanio overseeing the project.
Stephen Kalyn is also set to star in Season 2 of Off Campus, underscoring his rising profile beyond The Housemaid’s Secret.
Variety notes that production is expected to start later this year, with some reports indicating filming is already underway, signaling a potential shift in the production timeline.
TheWrap reports The Housemaid grossed roughly $400 million worldwide during the prior holiday season, highlighting Lionsgate’s incentive to expand The Housemaid into a broader franchise if The Housemaid’s Secret succeeds.
Stephen Kalyn has joined the cast of The Housemaid's Secret, Lionsgate's sequel to last year's blockbuster hit. The 28-year-old Canadian actor, known for Off Campus and Gen V, will play Brock, the lawyer boyfriend of Sydney Sweeney's character Millie. Yahoo News reports that Kalyn's addition expands an ensemble that includes Kirsten Dunst and returning cast members.
The original Housemaid grossed roughly $400 million worldwide during the holiday season, TheWrap noted, giving Lionsgate strong incentive to build the franchise. The sequel, directed by Paul Feig, is set for release on December 17, 2027, with production already underway based on Freida McFadden's bestselling novel.
Kalyn's casting marks a significant career milestone. People highlighted his growing profile through television roles in Off Campus and the superhero series Gen V. He will portray Brock, Millie's boyfriend who remains unaware of her darker secrets. The part positions him alongside established stars in what could become a major film franchise.
The original film became a surprise hit, pulling in approximately $400 million globally during last year's holiday window. That success has convinced Lionsgate to greenlight a sequel and explore building The Housemaid into a broader franchise if this installment performs well. The studio is banking on the story's dark secrets and locked-door mystery to draw audiences again.
Paul Feig returns to direct The Housemaid's Secret, with Rebecca Sonnishine adapting the screenplay. The production team brings back Carly Elter as executive producer, along with Alex Young from Hidden Pictures also executive producing. Lionsgate executives Chelsea Kujawa and Maria Ascanio oversee the project alongside co-producers from the original film.
Sydney Sweeney reprises her role as the mysterious housemaid Millie. Kirsten Dunst plays Mrs. Garrick, with Paul Anthony Kelly as her husband Douglas. Returning cast members include Brittany Snow as Marybeth and Michele Morrone as Enzo, maintaining continuity from the first installment.
