On Sunday, a special walk to honor Romero might make it into the Guinness Book of World Records.
Hundreds of wannabe zombies shuffled through the halls of the Monroeville Mall in an attempt to beat the world record for largest zombie walk.
Parts of Romero's "Dawn of the Dead," the sequel to "Night of the Living Dead," were shot at the mall in 1977.
Just like in the movie, zombies subsist on human brains, but, they're helping those who need more than just grey matter to survive.
"All zombies were encouraged to bring a canned food item with them, and I'm also here to eat some brains," said zombie Ryan Dolton, of Donora.
Before entering, the zombies went through make-up, and dropped off the food items for the Greater Pittsburgh Food Bank.
Zombies were encouraged to stay in character by just shuffling about, murmuring the word, "Brains." That meant no technology, cell phones or cameras.
As for the record, "I think we got it doubled at this point," said event organizer Professor MC Square. "Pittsburgh is the zombie capital of the world."
