Blood Feast, 1963

In Miami, a Middle Eastern caterer murders women and uses their body parts to re-create and revive an Egyptian goddess. On a nine-day shoot, and for about $20,000, director Herschell Gordon Lewis and producer David Friedman managed some pioneeringly gaudy special effects, notably a tongue-extraction sequence that had people going "Ewwwww!" for maybe the first time ever in a movie theater.
