The League of Extraordinary Gentlemen is a comic book series written by Alan Moore and illustrated by Kevin O'Neil. The series was launched in 1999 as part of the America's Best Comics imprint of Wildstorm Comics. The series spans two six-issues limited series and a hardcover graphic novel, with a third miniseries to be published by Top Shelf Productions. According to Moore, the initial concept behind the series was initially a "Justice League of Victorian England", but quickly grew into an opportunity to merge all works of fiction into one world.
Moore's work includes references to previous leagues and suggests there will be others subsequently. In much the same way that the New Traveller's Almanac, an appendix to the trade paperback collection of The League Vol. 2, detailed much of the geography of the Leagues world, the third volume, The Black Dossier, set out an extensive history of the world of the League and each of its various incarnations, threading together hundreds of disparate works of fiction into a cohesive timeline.
A film adaptation was released in 2003, also by the name The League of Extraordinary Gentlemen, and stars Sean Connery.
