FX has officially greenlit Seven Sisters, a new drama led by Elizabeth Olsen, for a full series order that will stream on Hulu in the United States and internationally on Disney+.

The show, created by playwright Will Arbery, centers on a large family whose close bond begins to fracture when one of the sisters starts hearing a mysterious voice that no one else can detect. As the situation unfolds, buried secrets and tensions within the family gradually surface.

Olsen stars alongside Cristin Milioti and J. Smith-Cameron. The ensemble cast also features Anthony Edwards, Meredith Hagner, Odessa Young, Zoë Winters, Bridget Brown, Carolyn Kettig, Philip Ettinger and Ryan Eggold.

Arbery executive produces the series with Garrett Basch and Sean Durkin, who directed the pilot episode. The project reunites Olsen and Durkin, who previously collaborated on the film Martha Marcy May Marlene. Smith-Cameron also reconnects with Arbery after working together on Succession.

FX Entertainment president Gina Balian praised the project in a statement, saying, “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. 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.”

The new drama joins a growing slate of FX projects, including recently announced and returning titles such as Far Cry, Alien: Earth, and The Lowdown.
