Hear from Executive Producers Frank Darabont and Gale Anne Hurd about what attracted them to the comic book series, and why AMC proved the perfect network to bring it to life. Learn from Production Designer Greg Melton what it takes to turn downtown Atlanta into an apocalyptic wasteland, and from Consulting Producer and Special FX Make-Up Designer Greg Nicotero what makes The Walking Dead's walkers so unique. The Walking Dead comic creator Robert Kirkman and artist Charlie Adlard, meanwhile, share their amazement over how true to the series the television show is, and how the actors' physcial similarities to their sketches inspired the Comic Con poster. The cast weigh in on the series as well, with Andrew Lincoln (Rick), Jon Bernthal (Shane), Laurie Holden (Andrea) and Sarah Wayne Callies (Lori) all praising the strength of the ensemble. "When we had our first group scene," Bernthal reflects, "I just looked looked around, I was like, 'Oh my God. There is not a weak link in this group.'"
