Sydney Sweeney is back at work as Millie Calloway, and a wealthy household is waiting for her. New set photos and videos show the actress filming The Housemaid's Secret alongside Michele Morrone, who returns as Enzo. The footage offers an early glimpse of the sequel to The Housemaid, Paul Feig's adaptation of Freida McFadden's bestselling thriller. Millie's next job comes with an unsettling condition: she must keep house for a woman she is never allowed to see. For anyone familiar with her first employers, an apparently comfortable home is hardly a promise of safety.
