Actor Stephen Kalyn, known for his breakout role in Amazon Prime Video's "Off Campus", has signed on to join Sydney Sweeney in Lionsgate's "The Housemaid's Secret". The film is a sequel to the studio's hit adaptation of "The Housemaid" and reunites much of the creative team behind the original, with Paul Feig directing and Sweeney also serving as a producer through her Honey Trap banner.

The cast also includes Kirsten Dunst, Brittany Snow and Paul Anthony Kelly. Sweeney reprises her role as Millie Calloway, who takes a housekeeping job for a woman she is never permitted to see, only to uncover dark secrets behind a locked door. Rebecca Sonnenshine, who wrote the first film, returns to adapt the sequel, while Todd Lieberman, Laura Fischer and Feig are among the producers. Kalyn, who has also appeared in "Gen V", "Cruel Intentions" and "Motorheads", is represented by CAA, Play Management, Thruline Entertainment and Goodman, Genow, Schenkman, Smelkinson & Christopher.
