Cristin Milioti (The Penguin, How I Met Your Mother) will star opposite Elizabeth Olsen in FX’s Seven Sisters.

In the drama series, “a large, tight-knit family begins to unravel when a sister (Olsen) starts communicating with a voice no one else can hear, forcing them to confront long-buried secrets.”

Milioti will play Olsen’s sister in the show.

Seven Sisters is executive produced by Will Arbery, who wrote the pilot; Sean Durkin, who will direct it; and Garrett Basch.
