Exclusive: HBO and Guillermo del Toro are teaming on Monster, developing a potential series culled from a series of 18 volumes of Japanese Manga by author Naoki Urasawa published by Shogakukan Inc. Del Toro will co-write the story with Steven Thompson , best known for his work on Doctor Who and Sherlock. Thompson will write the pilot, which del Toro intends to direct. The thriller is about the worldwide search by a young doctor for the most evil sociopath that has ever lived. He is a 12-year-old boy, and the doctor’s decision to save his life has unwittingly unleashed a Pandora’s Box that leaves the doc battling to stop a plot of mass genocide. This is certainly a departure for HBO, entering the Manga game, but for del Toro and Thompson, it allows them an incredible sandbox to play in. Del Toro will be executive producer and Thompson co-executive producer,
