The upcoming film adaptation of Audrey Niffenegger's bestselling novel Three Incestuous Sisters "is adding some serious star power," Deadline reported: Dakota Johnson (Materialists), Saoirse Ronan (The Outrun), Jessie Buckley (Hamnet), and Josh O'Connor (Knives Out series, Wake Up Dead Man) will star in the project. Alice Rohrwacher (La Chimera) is directing from a script she wrote with Ottessa Moshfegh that "is loosely based on the book." Niffenegger is also the author of The Time Traveler's Wife.
The film will be financed and produced by Indian Paintbrush. Johnson and Ro Donnelly will produce for TeaTime Pictures, along with Steven Rales for Indian Paintbrush. Rohrwacher will also produce. Principal photography is set to begin in April.
