Alice Rohrwacher finds her Three Incestuous Sisters: Dakota Johnson, Saoirse Ronan, and Jessie Buckley

For what it’s worth, Niffenegger’s 2005 adult fairy tale follows the sisters, Bettine, Ophile, and Clothilde, who move from their isolated home by sea to Paris. There, they meet a lighthouse keeper’s son, who reportedly “profoundly affects each sister emotionally.” Like other works by Niffenegger, the book is a “novel in pictures” that was compared to Edward Gorey. If the film follows any of that structure, we’re going to go ahead and predict that O’Connor plays the lighthouse keeper’s son. 

This marks Rohrwacher’s second collaboration with O’Connor, who starred in her last film, La Chimera, as an emotionally distant and quasi-magical graverobber. In addition to great acclaim, the film enjoyed an impressive 25-week run at the IFC Center in New York.
