Dylan Dog is an Italian horror comics series created by Tiziano Sclavi and published by Sergio Bonelli Editore since 1986. The series features the eponymous character, a paranormal investigator who takes on cases involving supernatural elements such as ghosts, demons, vampires, undeads, werewolves and other creatures, but also horrifying sociopathic criminals and serial killers. It defies the whole preceding horror tradition with a vein of surrealism and an anti-bourgeois rhetoric. Dylan is supported mainly by his trusty sidekick Groucho (a Groucho Marx lookalike) who adds humour to this grisly genre and Dylan's sombre temperament. The series is mainly set in London, where the protagonist lives, though he occasionally travels elsewhere. Dark Horse Comics has published the English version of Dylan Dog in the United States in 1999 and 2002. As of 2017, a new English edition was published by Epicenter Comics. The series has sold over 60 million copies worldwide, and is the second best-selling comic book in Italy after the Tex series, another publication by Sergio Bonelli Editore, with over 120,000 copies sold each month. The film Cemetery Man (original title: Dellamorte Dellamore, 1994) starring Rupert Everett, was loosely based on the comics, but its main reference was Tiziano Sclavi's novel Dellamorte Dellamore. A direct film adaptation, Dylan Dog: Dead of Night, starring Brandon Routh, was instead released in 2011, but it was significantly different from the source material. A television series based on the comics is also in development.
