Nicolas Boukhrief is a French writer and producer who helped write both the treatment and the final script for Silent Hill.
Nicolas has directed several small French films, such as Gardiens de l'ordre, Le Convoyeur, and Va mourire. He is also a writer and actor, and has worked in casting.
Nicolas is a close personal friend of director Christophe Gans, and so was contacted by Christophe when he became interested in making a film adaptation of the popular horror survival game Silent Hill. Nicolas aided Christophe in writing the film's treatment, and later helped write the final script with Christophe and Roger Avary. For reasons unknown, neither Nicolas nor Christophe are given writing credit for the film.
