Before Watchmen

Before Watchmen is a series of comic books published by DC Comics in 2012. Acting as a prequel to the 1986 12-issue Watchmen limited series by writer Alan Moore and artist Dave Gibbons, the project consists of eight limited series and one one-shot (though two were initially planned) for a total of 37 issues.

Moore stated in 1985 that if the Watchmen limited series was well-received, he and Gibbons would possibly create a 12-issue prequel series called Minutemen featuring the 1940s superhero group from the story. DC offered Moore and Gibbons chances to publish prequels to the series, such as Rorschach's Journal or The Comedian's Vietnam War Diary, as well as hinting at the possibility of other authors using the same universe. Tales of the Comedian's Vietnam War experiences were floated because The 'Nam was popular at the time, while another suggestion was, according to Gibbons, for a "Nite Owl/Rorschach team" (in the manner of Randall and Hopkirk (Deceased), and also in the sense that the original Charlton characters Blue Beetle and The Question had worked together as a team from time-to-time). Neither man felt the stories would have gone anywhere, with Moore particularly adamant that DC not go forward with stories by other individuals. Gibbons was more attracted to the idea of a Minutemen series, because it would have "[paid] homage to the simplicity and unsophisticated nature of Golden Age comic books—with the added dramatic interest that it would be a story whose conclusion is already known. It would be, perhaps, interesting to see how we got to the conclusion."

In 2010, Moore told Wired that DC offered him the rights to Watchmen back earlier that week, if he would agree to prequel and sequel projects. Moore said that "if they said that 10 years ago, when I asked them for that, then yeah it might have worked ... But these days I don't want Watchmen back. Certainly, I don't want it back under those kinds of terms." DC Comics co-publishers Dan DiDio and Jim Lee responded, "DC Comics would only revisit these iconic characters if the creative vision of any proposed new stories matched the quality set by Alan Moore and Dave Gibbons nearly 25 years ago, and our first discussion on any of this would naturally be with the creators themselves."
