Entitled “Rick’s Gun,” “Hospital Corridor” and “Darkness,” inside you’ll find the first three TV spots for AMC’s The Walking Dead, all of which will begin to air this coming week. The Frank Darabont-directed pilot airs on Halloween night. It kicks off the initial 6-episode first season. “The Walking Dead” tells the story of the weeks and months that follow a pandemic zombie apocalypse. County Sheriff Rick Grimes travels with his family and a small group of survivors, constantly in search of a safe and secure home. But the constant pressure of fighting off death on a daily basis takes a heavy toll, sending many to the lowest depths of human cruelty. As Rick struggles to keep his family alive, he will discover that the overwhelming fear of the survivors can be far more dangerous than the mindless walkers roaming the earth.
