Julianne Moore, Meghann Fahy, and Milly Alcock are set to star in the upcoming Netflix limited series 'Sirens,' a dark comedy created by Molly Smith Metzler and executive produced by LuckyChap. The show revolves around Devon's concerns about her sister Simone's troubling relationship with the socialite Michaela Kell, exploring themes of women, power, and class over a weekend at a luxurious beach estate. Metzler's play 'Elemeno Pea' serves as the basis for the series, with Nicole Kassell directing the first two episodes. The project marks the first collaboration between Metzler and Netflix, following her success with 'Maid,' and features a talented cast including Moore, Fahy, and Alcock.
