Cannibal Holocaust
Splatter films have pioneered techniques used in other genres. For example, the popular 1999 film "The Blair Witch Project" is similar to the 1980 film "Cannibal Holocaust". The story in "Cannibal Holocaust" is told through footage from a group of people making a documentary about a portion of the Amazon which is said to be populated by cannibals. Although the "Blair Witch" directors had not seen "Cannibal Holocaust" at the time of filming, this "mockumentary" format was later used in their film.
