Snuff movies do not exist.
For anyone genuinely interested in whether any of the footage in this film is real, I'd recommend the excellent 'Killing For Culture: An Illustrated History of Death Film from Mondo to Snuff'(Creation Books) by David Kerekes and David Slater. It has an extremely well-researched and highly readable chapter on the 'F.O.D.' series, as well as a definitive debunking of the authenticity of 'Snuff' and the Japanese 'Guinea Pig' series, among many others.
