Researching for a novel I came across this account of the filming of George Romero’s masterpiece, Dawn of the Dead. Everything I really need to know I learned in kindergarten, and one of those things was to share:
Once the zombies did get a quick meal their feast had to be graphically shown. The raider Sledge, played by Stavrakis, gets his abdomen ripped open by a mob of zombies. Savini sculpted a false chest appliance and glued it to Stavrakis from his groin to his neck. Blood tubing and actual sheep intestines were sealed inside. All the extras would have to do is rip the foam abdomen open.
Anyone who would actually stick these entrails in their mouths were shot for gross-out close-ups. Whenever zombies ate what looked to be human entrails, they were actually gnawing on hams, hot dogs or other deli meats. One extra, a pregnant lady, proposed having the zombies rip her open and a fetus falling out. This idea was too shocking even for Romero and Savini.
