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.
Rick Grimes
Executive producer Gale Anne Hurd initially didn't expect Lincoln to portray Grimes. Upon hearing the announcement, Writer Robert Kirkman felt that Lincoln was an "amazing find" and added that he accurately embodied the characteristics of Rick Grimes. "Writing Rick Grimes month after month in the comic series, I had no idea he was an actual living, breathing human being, and yet, here he is. I couldn't be more thrilled with how this show is coming together." Although he was initially shocked upon hearing of the concept of "The Walking Dead", Lincoln thought that the script for "Days Gone Bye" was well written. He stated: "I read it and thought it was well written, and I put myself on tape just for one scene. I didn't know who was involved at this point." The following day, Lincoln's agent called him about the development of the pilot, to which Lincoln called it "kind of like a dream list".
