Hunter × Hunter
Before the first anime television series was created, a short film adaptation of "Hunter × Hunter" was shown as part of the 1998 "Jump Super Anime Tour" alongside similar adaptations of "Seikimatsu Leader den Takeshi!" and "One Piece". Produced by Studio Pierrot and directed by Noriyuki Abe, it depicts the early events of the manga up to Gon's ocean voyage from Whale Island.

In 2013, it was revealed that Guillermo del Toro and American premium television network HBO were collaborating on a pilot for a live-action TV series based on "Monster". Co-executive producer Stephen Thompson ("Doctor Who" and "Sherlock") was writing the pilot, while del Toro was to direct it and be an executive producer alongside Don Murphy and Susan Montford. In 2015, del Toro told Latino-Review that HBO had passed on the project and that they are in the process of pitching to other studios.
