Kirsten Dunst (Civil War) has joined the cast of Paul Feig‘s The Housemaid’s Secret. She will play Wendy Garrick.

She joins Sydney Sweeney.

In The Housemaid’s Secret, Sweeney’s character Millie returns, this time taking a job keeping house for a woman she’s never allowed to see—only to discover the truth behind the locked door that threatens to expose secrets far darker than her own.

Lionsgate Motion Picture Group’s Erin Westerman said in a statement, “It is a privilege to bring The Housemaid’s next chapter to the screen with Kirsten Dunst. She is an icon. Her career reflects extraordinary range and fearlessness. Opposite the ever-magnetic Sydney Sweeney, she will be an electrifying force in a world where nothing is ever quite as it seems.”

Screenwriter Rebecca Sonnenshine, who adapted the first book, will also return to write The Housemaid’s Secret, based on the bestselling novel by Freida McFadden.

In The Housemaid, Millie, trying to escape her past, accepts a position as a live-in housemaid for a wealthy family. But what begins as a dream job quickly unravels into something far more dangerous — a sexy, seductive game of secrets, scandal, and power.
