"Cannibal Holocaust" is a film that is known by most and dismissed by many, especially by those who have never seen it. I was expecting to sit down to a graphic exploitation of human and animal suffering, with no purpose other than to provide cheap entertainment. This perception had put me off seeing the film for many years, but I was eventually persuaded to by someone who had seen it.
There are many different versions of "Cannibal Holocaust", most of which are cut to a lesser or greater extent. The Ultrabit version which I saw claims to be fully uncut, and from what I can gather online, this is the case. I believe that the BBFC have classified the film recently as an 18, with a brief cut to remove the scene of one of the animal killings. Frankly that seems a bit daft, the scene in question is no worse than others within the film.
There can be no doubt that many of the scenes are extremely graphic, with genuine scenes of animals being killed, and staged human mutilation, gang rape and miscellaneous sexual violence. These scenes will turn off many viewers (and undoubtedly turn on others), but none of them feel out of place within the film - an uncomprimising "documentary" looking at life among cannibal tribes in the Amazon region of South America.
The point of the film being a "documentary" is a key part of enabling the director - and the viewer - to explore the exploitation of the characters, and themselves. The film exploits exploitation, and satirizes the genre prevelant at the time. On a base level, animals are exploited for the viewer's entertainment, as are the tribal characters being presented as "unchanged in 4000 years". The exploration of the theme goes much further than this, however - everyone and everything is subjected to exploitation, and the director wants to make the viewer aware of this.
The "documentary" makers want to exploit the "cannibals" and indeed each other, in order to make their names famous, with no regard for the lives of their subjects or themselves. The tribes exploit the film-makers, feeding off their carcasses. American TV producers wish to exploit everyone, in order to get a high-rating show. Animals are exploited - for our entertainment, for the characters' needs. The viewer is left questioning why they are watching the film - is the viewer exploiting the actors and directors, or are they exploiting him or her?
"Cannibal Holocaust" is an important film, an enjoyable film, and well worth watching whether you have an interest in the genre itself, or in cinema history. Sadly, many viewers will not watch the film because of its reputation, even if the censor in their country allows them to.
