Faces of Death's subject matter is so macabre and unsettling that it works well as a horror film, while being officially a documentary (sort of; it combines real-life video with produced scenes).
Though Takashi Miike has produced a good number of scary, graphic, and frequently extravagant films that combine elements of action, crime, and/or horror, none of them have been as persistent as Ichi the Killer.
Even while those who have seen Braindead (also known as Dead Alive) agree that it is graphic, they may not think that it is so intense that it should be kept concealed from even adults. Nevertheless, the unedited version of the film was surprisingly banned in a number of areas.
The Devils can be violent and explicit, but it was also controversial for its sexual content and the way it examined religion. Most horror films are prohibited because of the amount of violence they contain.
Similar to The Devils, Salò, or the 120 Days of Sodom, is a 1970s film that has gained a reputation as one of the most horrifying movies ever made and continues to frighten and disgust viewers even after all these years.
A Serbian Film is certainly a contender for the title of most controversial and frequently banned film of the twenty-first century, even though it may not have the same notoriety as other scary films that were problematic decades ago and are still confronting now.
Cannibal Holocaust bears up to its reputation as one of the goriest horror films ever made, an early found-footage picture, and an extremely dark satire/social criticism.
I Spit on Your Grave is another movie that will never be forgotten. It has a revenge/thriller plot and many graphic moments that push it into the horror category.
Seeing a low-budget horror film succeed and become a legend can be motivating, particularly for aspiring filmmakers who wish to break into the business and gain notoriety but lack the resources to produce something highly complex.
