The title is taken from one of the original titles for Night of the Living Dead (1968), which was "Night of the Flesheaters".
Together with S. William Hinzman more or less reprising his role from Night of the Living Dead (1968), Vincent D. Survinski reprises his role as Vince, the posse gunman.
The cameraman filming the scene when the little angel zombie (Heidi Hinzman) is shot by the posse member was accidentally shot in the foot by the cardboard plug of the guns blank. The charge was more powerful than a normal blank and went through his shoe injuring his foot. This story was told by Bill Hinzman as a cautionary tale about making your own blanks.
In the "cardiectomy" scene, the heart S. William Hinzman bit into was supposed to be a plastic cast of a pig's heart. When something went wrong with the plastic cast, they had to throw the actual pig's heart in instead. Word was not relayed to Hinzman in time, who found himself biting into a pig's heart.
