The project, from author Kendare Blake, centers on Cas Lowood (Monaghan), who has inherited an unusual vocation: He kills the dead. So did his father, until he was gruesomely murdered by a ghost he sought to kill. Now, armed with his father’s mysterious and deadly dagger, Cas travels America with his mother and their spirit-sniffing cat. They follow legends and local lore, destroy the angry dead, and keep pesky things like plans for the future and friends at bay. Searching for a ghost the locals call ‘Anna Dressed in Blood’, Cas finds a girl entangled in curses and rage, a ghost like he’s never faced before.
Since her death, Anna (Hasson) has killed each and every person who has dared to step into the deserted Victorian house she used to call home, but yet there is something about Cas that compels her to spare his life. For reasons neither can explain, the two begin to realize that in their opposite, they may have finally found the one person who can help them unravel their complicated pasts, and survive their complicated present.
Twilight author Stephenie Meyer and Meghan Hibbett, will produce the film. Music video helmer Trish Sie will direct from a screenplay written by Allison Wood. The film is slated to begin principal photography in November.
