The Last Exorcism director Daniel Stamm has signed on to direct the English-language adaptation of French director Pascal Laugier's dark and violent Martyrs, about two teenage girls who are not what they appear to be, according to 24 Frames.

Martyrs tells the story of Lucie and Anna, orphans who establish a friendship, until one of them inexplicably goes on a murderous rampage to avenge what may or may not have been earlier incidents of child abuse.

"Martyrs is very nihilistic," Daniel Stamm said. "The American approach [that I'm looking at] would go through all that darkness but then give a glimmer of hope. You don't have to shoot yourself when it's over."

"Every time you think you know where it's going, it goes somewhere else. It plays on things that are familiar - like two friends who can't be separated, kind of a Forrest Gump and Jenny situation. But then it takes a turn, and in doing so asks interesting quesitons. 'If you have a best friend in the world and she goes crazy, how much do you owe this friend to go down with them?' It's much more than a horror film."

Daniel Stamm dismissed the Internet rumor that Kristen Stewart could be starring in the remake, laughing and quizzically saying that it's "the first time I've heard that."

No production date has been set.
