Author Freida McFadden says Sydney Sweeney was "exactly" what she imagined when writing The Housemaid, making her the perfect choice to star in the film. "She has the right vibe," McFadden, 45, told Us Weekly exclusively at the 2026 TIME100 Gala hosted at Lincoln Center in New York City on Thursday, April 23. "She has this great energy and passion." Sweeney, 28, played The Housemaid protagonist Millie in the film adaptation, which hit theaters in December 2025.
