13. The Stuff's Screaming Victim
Movie: The Stuff (1985)
In writer-director Larry Cohen's inventive yet cheaply made horror satire The Stuff, a strange white goo is mistaken for a tasty dessert by consumers, ingested, and starts pouring out their orifices and turning some into zombies. The damaging, fatal effects of the goo are goofily seen when one character (the poor bastard you see above) suddenly starts to convulse and howl as the stuff bubbles out of his mouth. And by "his," we do mean an actual human being, even though it's anyone's guess as to what the hell that hot woman is holding onto.
