Day of the Dead (1985)

Here's a scene from Day of the Dead (1985) with my favorite zombie, Bub.

This final chapter of George A. Romero's "Dead Trilogy" is even gorier than the first two "Dead" films - Night of the Living Dead (1968) and Dawn of the Dead (1978) - thanks to special makeup effects by gore master Tom Savini.

The blood and entrails used in the disemboweling of Capt. Rhodes were real. Pig intestines and blood were procured form a nearby slaughterhouse and used to make the scene. During filming the refrigerator housing intestines and blood was unplugged by custodial staff, and the entrails started to spoil causing most of those involved to become physically sick.
