Celluloid Nightmare (1999) – Daisuke Yamanouchi.

Popular Adult AV idol Mai Tsurumi's sudden, prolonged disappearance engenders rumours of her being abducted, and slaughtered in a 'Snuff' video, investigative Journalist (Yuki Emoto)digs resolutely into the case, discovering that Snuff is no mere Urban legend! Celluloid Nightmare's seamless mockumentary style proves enormously effective, drawing you ever deeper into the increasingly macabre mystery herein. The dramatic, thrillingly suspenseful lead up to the grisly revelation is satisfyingly rendered, with naturalistic performances from an altogether credible cast.

I think the suggestion that the increasingly extreme examples of fetishistic porn, and actual snuff being inextricably linked is not entirely specious, at which nexus point do violent sexual fantasies fatally intertwine with actual psychosis? The simulated, not so simulated abuse of women in sleazier pornography, if violently increased could culminate in death, and would demonstratively attract minions of the darkly curious. Sharp, concise, and wickedly penetrating, Celluloid Nightmare remains impactful, and disturbingly contemporary, keeping its sinister plot very close to its chest, right until the tantalizingly turny-twisted climax, which is now the snuff of legend!
