AMC’s The Walking Dead presence here on Day 2 of this year’s San Diego Comic-Con kicked off with moderator Chris Hardwick (The Talking Dead) introducing the panel, including executive producers Robert Kirkman, David Alpert, Greg Nicotero, Gayle Anne Hurd, and showrunner Glen Mazzara, and debuting the trailer for the upcoming Season 3 (which you can watch here below).

Kirkman, who created the comic book series that the TV show is based on, said viewers can look forward to a fully stage-built yet realistic prison set. Alpert said that the series has exceeded the vision he had in his head from the comic book. Hardwick mentioned that naysayers who complained about lack of zombies early in season two, certainly had nothing to complain about by season’s end. Nicotero said he’s striving to create more realistic decomposed and hungry zombies moving forward in The Walking Dead‘s timeline. He wants to keep the audience guessing with what effects they’re going to unleash. He’s recently directed his first episode and felt it rewarding to him to finally connect with the actors.
