Premise from wikipedia:
A small-town Oregon teacher and her brother, the local sheriff, become entwined with a young student harboring a dangerous secret with frightening consequences.
Keri Russell will play the teacher while Jesse Plemons will play her brother. Jeremy T. Thomas is playing the student.
So, I hope you keep this film in your radar as well as Nick Antosca's short story. I'm glad to hear more short stories and novellas are being made to movies. Hopefully, in the near future, I'll announce that my novellas/short stories are being optioned:) One can hope and pray until it comes to fruition. Take care and thanks for stopping by again.
Update: You can read the entire short story of The Quiet Boy by clicking the title itself. You can enjoy that little read while eagerly awaiting for the film adaptation.
