The Housemaid film adaptation was pretty spot on to Frieda McFadden's novel of the same name. The movie, starring Sydney Sweeney and Amanda Seyfried, hit theaters on Friday, December 19, and viewers were shocked by those brutal twists. While readers were already privy to the secrets of The Housemaid, director Paul Feig still found a way to make things jarring for those who already knew what was coming. Both the book and movie follow the story of a young housemaid named Millie (Sweeney), who moves into Andrew (Brandon Sklenar) and Nina Winchester's (Seyfried) home as hired help.
