In the end, AMC has cast Andrew Lincoln (pictured below) as the lead in its zombie apocalypse thriller “The Walking Dead,” the Frank Darabont adaptation that goes behind camera this June in Atlanta. Jonny Lee Miller has been the original frontrunner. Lincoln (“Teachers,” “Enduring Love”) will play Rick Grimes, a small-town cop who leads a group of survivors in their struggle against a world besieged by zombies. As previously announced, Jon Bernthal will play Shane, a survivor who was Rick’s police partner before the zombie disaster. “Andrew Lincoln, wow — what an amazing find this guy is,” said Robert Kirkman, who wrote the comic book series upon which the series is based. “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.” AMC has already ordered 6 episodes.
