The big screen adaptation of the Kristin Hannah’s best-selling book The Nightingale has found its lead sisters in real-life sisters Dakota and Elle Fanning.

Dakota and Ella Fanning have both forged their own distinct paths to stardom, but the two will now be combining their talents to play sisters on the big screen.

The Wrap broke the news today that the real-life sisters have been cast to play sisters in the upcoming TriStar Pictures’ adaptation of Kristin Hannah’s best-selling 2015 novel The Nightingale.

Though Elle played a younger version of Dakota’s character in the 2001 film I Am Sam, this will mark the first time the two have appeared together on screen.

“The Nightingale will be the first time we act on screen together. We have played the same character at different ages but have never spoken to each other in front of a camera. For years, we have looked for a film to do with one another and then this gem appeared,” the Fannings said in a joint statement. “As sisters, to share our artistry with each other while bringing such a powerful sister story to life is a dream come true. We are so lucky to have our fearless director, Mélanie Laurent, to guide us along on the journey. Let’s do this, sister!!”

The Nightingale tells the story of two French sisters on the eve of World War II. The sisters struggle to survive the German occupation of France and resist Nazi rule, each reacting to and taking action in their own separate ways. Though the story and sisters are fictional, parts of the story, such as one of the sisters helping downed Allied pilots escape the Germans, are inspired by actual historical events.

Melanie Laurent, who worked with Elle Fanning on the drama Galveston, will direct from a script by Dana Stevens. Elizabeth Cantillon is producing through her Cantillon Company banner.
