Days Gone Bye (The Walking Dead)
Robert Kirkman, the creator of the eponymous series of comic books, considered the idea of creating a television show based on the comic series, but did not move forward. Frank Darabont expressed interest in developing the series for television. In January 2010, AMC formally announced that it had ordered a pilot for a possible series adapted from "The Walking Dead" comic book. In the announcement, the executives stated that Darabont would serve as writer, director, and an executive producer alongside Gale Anne Hurd.

The original pitch by Kirkman and Moore was for a followup to George A. Romero's "Night of the Living Dead", with the series taking place in the 1960s. Image Comics co-founder Jim Valentino suggested using an original concept instead so the creators would own the property outright. The revised pitch became "The Walking Dead."
