Deadline Hollywood has reported that HBO is in talks with Guillermo Del Toro (Hellboy, Pan’s Labyrinth) to develop a TV series based on the manga Monster.
Del Toro will be co-writing with Stephen Thompson (best known for his writing on Doctor Who and Sherlock.) The project was originally planned for a feature film, but proved too complicated to fit into a normal feature-length time frame. Del Toro was eventually able to convince Naoki Urasawa, the author of Monster, to talk to HBO about a TV series instead.
