By now I'm sure you've heard of Gillian Flynn's runaway bestselling book Gone Girl, but that's not the only Flynn adaptation that's creating buzz. Dark Places is also getting the big screen treatment, and it's been amassing a stellar cast, making news this week for switching the role that Christina Hendricks will play. The darker murder mystery centers on Libby, a woman who's still haunted by the brutal killings of her mother and sisters when she was a child — and the fact that her testimony put her brother behind bars for the crime. In present day, however, a group of people want to reopen the case with new findings that make Libby question everything. If you've read Dark Places, you'll definitely want to see which faces are taking on Flynn's characters. See who Charlize Theron, Nicholas Hoult, and more are playing!
