HBO is developing a new limited series based on Dark Places, the bestselling 2009 novel written by Gone Girl and Sharp Objects author Gillian Flynn. All three of Flynn's popular mystery novels have received onscreen adaptations: the 2014 Gone Girl film starring Ben Affleck and Rosamund Pike, the 2015 Dark Places film starring Charlize Theron, and the 2018 HBO limited series adaptation of Sharp Objects starring Amy Adams. While the Gone Girl and Sharp Objects adaptations received mostly positive reviews, the Dark Places film was critically panned.
