Amidst a resurgence in her career, actress Sydney Sweeney is poised for significant roles in upcoming films. Her performance in The Housemaid demonstrated remarkable range, setting the stage for more complex characters. Notably, her upcoming role in Scandalous as Kim Novak has garnered attention, though The Custom of the Country promises even greater challenges. This period drama, based on Edith Wharton's seminal work, marks Sweeney's first major lead in a cinematic adaptation. Co-produced by her own company, Fifty-Fifty Films, alongside esteemed studios, the project features Sweeney as Undine Spragg—a cunning social climber navigating the opulent yet treacherous world of late 19th-century New York. Directed by Sofia Coppola, the film explores themes of ambition and societal hypocrisy, with Sweeney tasked with translating Wharton's intricate narrative to the screen. The adaptation, currently in production in Lisbon, Portugal, under the helm of acclaimed filmmaker Josie Rourke, holds potential for both critical and commercial success.
