If you're a period drama fan, then there's a very good chance you've heard of Kristin Hannah's The Nightingale. The novel, which follows two sisters in France during World War II, made waves when it was first released in 2015.

Real-life sisters Dakota and Elle Fanning will finally share the big screen for the first time in the movie adaptation of Kristin Hannah's novel, The Nightingale.

The Nightingale is a very special movie because it's the first time ever that Dakota Fanning and Elle Fanning will star in scenes together. The only time they've ever been in the same movies before is when Elle played a younger version of Dakota's character, so this is a huge deal for fans of this duo!
