Zombies fill Monroeville Mall on Sunday morning to mark the 30th anniversary of the filming of George Romero's classic "Day of the Dead," which was filmed in the mall. The Monroeville Mall Zombie Walk will be part of World Zombie Day, with walks being held in more than 40 cities worldwide benefiting local food banks. "Day of the Dead" actor, Ken Foree, the famed zombie killer in the movie, led the march.
