Guinea Pig: Devil's Experiment

Guinea Pig: Devil's Experiment (1985) is a Japanese horror film you can watch online on iFILM. Forty-three minutes of mock-documentary footage: masked men abduct a woman and run systematic tests on how much pain a human body can endure. No plot. No characters. Just the record.

Shot on 8mm by a Japanese production company, this is the first entry in the cult Guinea Pig series. In the late 1980s, actor Charlie Sheen reportedly mistook the tape for genuine snuff footage and handed it to the FBI. Investigators confirmed it was staged — but by then the film's reputation as the most disturbing horror of the decade was already sealed.
