Too early for Halloween plans? Not really. The Walking Dead TV show debuts on Halloween at 10 PM ET with a 90-minute opening episode. Based on Robert Kirkman’s comics, the show follows the adventures of the survivors of a zombiepocalypse, and stars Andrew Lincoln, Jon Bernthal, Shane Walsh, and Sarah Wayne Callies. The four-and-a-half minute trailer previously seen at Comic-Con was also released, and we would absolutely set our DVR for this while we were out trick or treating!
