Julianne Moore toes the line between enigmatic socialite and cult leader in the new trailer for Sirens, a new limited series premiering May 22 on Netflix.

In the series, Moore plays the wildly wealthy, but mysterious Michaela Kell, who presides over her luxurious seaside estate, Cliff House, with a rather unsettling air (there’s kind of a Wicker Man/Midsommar in Lily Pulitzer vibe to the whole place). Meanwhile, Milly Alcock plays Michaela’s devoted assistant, Simone, who has become deeply enthralled with all this wealth and developed an exceptionally strange relationship with her boss.

In one wild moment, Simone asks Michaela (or “Kiki”) if her breath smells, and Michaela responds by saying, “Take my gum” — before taking a piece of gum out of her mouth and feeding it to Simone. 

Things start to go awry, though, when Simone’s sister, Devon (Meghann Fahy), shows up at Cliff House. The trailer hints at some tumult and mystery in the DeWitt family’s past, though it centers largely on Devon’s efforts to get Simone to snap out of the hold Michaela has on her: “This Michaela bitch has her talons so deep in your brain that you can’t even tell you’re in trouble,” Devon warns at one point. 

Along with Moore, Alcock, and Fahy, Sirens also stars Kevin Bacon as Michaela’s billionaire husband, Peter Kell, and Glenn Howerton as a fellow wealthy neighbor, Ethan Corbin III. Other cast members include Bill Camp, Josh Segarra, Felix Solis, Britne Oldford, Lauren Weedman, and Jenn Lyon.

Sirens was spearheaded by Molly Smith Metzler, and it’s based on her play, Elemeno Pea. Metzler was also behind the 2021 Netflix miniseries, Maid, starring Margaret Qualley.
