New Gillian Flynn Adaptation in the Works at HBO

Another Gillian Flynn mystery novel is getting an adaptation following the success of the 2014 film Gone Girl and the 2018 limited series Sharp Objects.

Her second novel, Dark Places, will be heading to HBO, where Flynn will co-create, write, and co-show run the limited series alongside Brett Johnson.

Published in 2009, Dark Places follows Libby Day, whose family was murdered in the infamous 1985 Kansas 'Satan Sacrifice.' She testified her brother did it. Twenty-five years later, detectives tell her he's innocent and pump her for details, hoping to profit off her tragic history.

Guerrin Gardner will also co-create and write on the show with Blue Marble Pictures' Theresa Kang and Caroline Garity executive producing alongside Iervolino & Lady Bacardi Entertainment's Andrea Iervolino and Monika Bacardi.

This won't be the first adaptation of Dark Places, as it was first a feature film starring Charlize Theron. Only grossing $5.1 million, the film didn't mirror the success of Gone Girl and Sharp Objects.

Sharp Objects, starring Amy Adams, was nominated for eight Primetime Emmys and followed a crime reporter who returns to her hometown to solve the murder of two young girls.

Gone Girl, directed by David Fincher, follows a man who sees the spotlight turned on him when his wife disappears, and it's suspected that he may not be innocent.

Further information, such as casting and else will be involved, is still to be announced.

Variety was first to report the news.
