A new Dungeons and Dragons movie based on Book of Vile Darkness is in production for Syfy, according to Wizards of the Coast. Like Wrath of the Dragon God, which was released on DVD in 2005, Book of Vile Darkness is being produced by Zinc Entertainment. 
Book of Vile Darkness, written by Monte Cook, is one of the very few D&D sourcebooks released by WotC marked for mature readers.
