A movie adaptation of Lady Killer, the Dark Horse comic by Joëlle Jones and Jamie S. Rich, is heading to Netflix. Blake Lively is set to star in and produce the film with Oscar winning writer Diablo Cody set to pen the script.

Lady Killer is a horror twist on the idyllic 1950s family sitcom. It follows Josie Schuller, a perfect housewife and mother who is hiding a pretty big secret. When she’s not taking care of her family she leads a secret life as a contract killer. And since Josie really loves her job and doesn’t stick to the cleanest methods of assassination, some of her crime scenes get very bloody. Lively is set to play the lead role of Josie.

Along with Lively, the movie will be produced by Mike Richardson and Keith Goldberg of Dark Horse Entertainment and Kate Vorhoff of B for Effort.

The first volume of Lady Killer was introduced in January 2015. A year later it earned an Eisner Award nomination for Best Limited Series.

A release date or other casting news was not announced.
