(May 1, 2009)
The American film studio Warner Brothers has acquired the rights to adapt Tsugumi Ohba and Takeshi Obata’s Death Note supernatural suspense manga series into a live-action film. In the manga, a teenager finds a notebook with which he can put people to death by writing their names. He begins a self-anointed crusade against the criminals of the world, and a cat-and-mouse game begins with the authorities and one idiosyncratic genius detective. In the proposed film version, the main character is described as a college student, and the story will cover the first three of the 13 manga volumes.
