blood feast (1963)

aka Egyptian Blood Feast. Feast of Flesh.
A small town is being terrorised by a serial killer, who specialises in young women and taking various body parts. Meanwhile Dorothy Fremont is throwing a party for her daughter Suzette and calls in a local caterer, Fuad Ramses. He promises to prepare her an Egyptian feast not prepared for 5,000 years. Unfortunately for Suzette, Fuad is the killer. For he needs the body parts to help resurrect the Godess Ishtar at a ceremony he will perform at Suzette's party.
The godfather of gore's meisterwork, the one he will be remembered for, that changed the rules of horror cinema forever. Before this films shied away from showing anything too explicit, but Herschell realised that people wanted to see the gore. So gore he gave them. Lashings of over the top gore. If you like extremely low budget films with, trashy, campy acting, bizzare plots, gore and lots of it: all filmed in stunningly bright colours, then this is for you.
