The 1970s is generally considered one of the finest decades in cinema history, and it was a fertile time for the horror genre as well.
You know the classics, of course: movies like The Exorcist, The Omen, Halloween, The Texas Chain Saw Massacre, The Hills Have Eyes, Dawn of the Dead, Carrie and others all became horror landmarks, while even old staples like British studios Hammer and Amicus were still making some interesting fare.
But the '70s are also memorable for the wealth of lesser known horror films that emerged from that tumultuous decade. Some went on to become bona fide cult classics, while others were remembered only by horror diehards and historians. Many were forgotten or unavailable for years, but thanks to specialty Blu-ray houses like Scream Factory and Severin, and streaming video services like Netflix and Amazon, you can see almost all these movies today, often in pristine or restored condition.
This list of horror's more obscure '70s delights could easily be twice as long -- we had to make some tough choices just to whittle it down to 20. But each of these movies is creepy, weird, sometimes distasteful but definitely memorable -- a tribute to what may still stand as horror cinema's greatest decade.
