The Walking Dead: 16 Easter Eggs You Probably Missed In Season 5

6. George Romero's Crate

Only the most astonishingly eagle-eyed of fans - equipped with theses in Zombie entertainment lore - could ever have spotted this reference. Luckily special effects make-up supremo Greg Nicotero divulged in an interview with the Walker Stalker Podcast that there was a special George Romero reference in the first episode:

"In episode 1 for this season, when Rick and the guys are running to the train car to let the crazy tattooed guy with long hair out, one of the crates in the foreground says 'Horlicks University via Julia Carpenter. That's from George Romero's film Creepshow. It was written on that crate, like the creature was inside."

Nicotero also conceded that he's now just hiding references in for the hell of it:

"Now I'm starting to get a little rambunctious and putting little nods in there that don't have anything to do with zombies, but just stuff that inspires me. I love throwing them in there. I never really put them in there hoping people would notice them. I put them in there as a reiteration of my respect and admiration for the genre."
