EXCLUSIVE: Seven Sisters, the FX drama pilot with a stacked cast led by Elizabeth Olsen, Cristin Milioti and J. Smith-Cameron, has received a series order. The project, from writer Will Arbery, director Sean Durkin and producer Garrett Basch, also stars Odessa Young (Springsteen: Deliver Me from Nowhere), Succession‘s Zoë Winters, Meredith Hagner (Bad Monkey), New Amsterdam‘s Ryan Eggold, ER alum Anthony Edwards as well as Bridget Brown, Carolyn Kettig and Philip Ettinger.

Seven Sisters, from FX Productions, follows a large, tight-knit family that begins to unravel when one sister, Adrienne (Olsen), starts communicating with a voice no one else can hear, forcing them to confront long-buried secrets.

Olsen, newly minted Emmy winner Milioti, Hagner, Young, Winters, Brown and Kettig play the titular sisters; Ettinger plays their brother; Edwards and Smith-Cameron portray the octet’s parents; Eggold plays Adrienne’s husband.

Seven Sisters is executive produced by Arbery, who wrote the pilot; Durkin, who directed it; and Garrett Basch. The pilot reunited Olsen and Durkin a decade and a half after the award-winning 2011 movie Martha Marcy May Marlene, written and directed by Durkin in his feature directorial debut, which starred Olsen in her feature debut.

This marks Basch’s fifth series for FX, where his company Dive has a longstanding first-look deal, following Devs, Reservation Dogs, What We Do in the Shadows and The Lowdown. He also is executive producing FX’s comedy pilot Very Young Frankenstein.

“We’ve been on the lookout for a compelling family drama, and when Will Arbery and Garrett Basch brought us Seven Sisters, we found one that felt uniquely FX,” said Gina Balian, President, FX Entertainment. “It lives in the deep relatable dynamics of adult siblings and their parents but does so in a way that’s bold and original with an unexpected twist. This group of incredibly gifted actors brings this family’s secrets to life in a way that will draw audiences in and keep them guessing until the very end.”

Seven Sisters was one of two drama pilots greenlighted by FX in March. The other, a Snowfall spinoff starring the original series’ Gail Bean and Isaiah John, was picked up to series last month.
