BWW Review: VAMPYR at the Ace Hotel TheatreCarl Theodore Dreyer and Christian Jul wrote VAMPYR, basing it on aspects of Sheridan Le Fanu's 1872 publication, IN A GLASS DARKLY, a collection of five short stories of mystery and the supernatural. Subtitled THE DREAM OF ALAN GREY, the movie tells of a young man's strange experiences in the North-Central French village of Courtempierre. They may have been real or just dreams, we cannot be sure.
