Stephen Kalyn Joins Lionsgate Sequel The Housemaid’s Secret

The casting links a rising performer to a Paul Feig‑directed follow-up with a set Dec. 17, 2027 theatrical date that advances Lionsgate’s fast-moving thriller franchise plan.

Overview

  • On Monday, August 31, 2026, Lionsgate announced that Stephen Kalyn has joined the cast of The Housemaid’s Secret in a role the studio shared via social and trade outlets.
  • Kalyn will play Brock, a lawyer who becomes Millie Calloway’s romantic partner and is written as someone unaware of her criminal past.
  • The production keeps the original creative team intact with Paul Feig directing, Rebecca Sonnenshine returning to adapt Freida McFadden’s novel, and Sydney Sweeney set to reprise Millie and serve as a producer.
  • Lionsgate plans to begin production later in 2026 with a planned wide theatrical release on December 17, 2027.
  • The sequel is part of a deliberate franchise push after The Housemaid grossed roughly $400 million worldwide and Kalyn’s casting leverages his breakout profile from Prime Video’s Off Campus to broaden the series’ commercial appeal.
