Elle Fanning has revealed there is still hope for her movie collaboration with her sister Dakota Fanning. In late 2019, it was announced that the real-life siblings would play sisters in the movie adaptation of Kristin Hannah's 2015 novel The Nightingale. The movie was in pre-production when the pandemic hit in 2020 and its release date kept being pushed back, leading many to wonder if it had been scrapped for good.
