* VindicatedByHistory: Caused a lot of damage to Mario Bava's career due to it's unflinching depictions of carnage. Creator/ChristopherLee reportedly even walked out of the screening disgusted with the violence. But, it's now regarded as providing the blueprint for the 80s SlasherMovie. A lot of it's kills have been imitated, ripped off, spoofed and homaged most notably by ''Film/FridayThe13thPart2'' but this one still retains it's power to shock.
