The project is based on the horror comic book series created by Tim Seeley and Stefano Casselli. The story centers on Cassie Hack, a young woman who epitomizes the surviving female character at the end of every horror movie. Now a trained killer, she travels the country, hunting down slasher-type serial killers, along with her protector, Vlad.
Hack/Slash has seen a number of screenwriters come and go, such as Todd Lincoln, Justin Marks, and Stephen Susco. It isn't known if Relativity will hire a new writer, or if they will work off an earlier draft.
Alexandra Milchan, Adrian Askarieh, and Daniel Alter will produce for Relativity. No production schedule was released.
