After the atrocious Ginî piggu 2: Chiniku no hana (1985), the notorious "Guinea Pig" series took an unexpected turn, introducing elements of slapstick comedy and sarcasm into the already controversial horror collection. To better understand the intricate latex effects and how exploding heads; detonating hearts; a zombie love story and a hilarious nail-pie fight were made in the series' fourth volume, Ginî piggu 4: Pîtâ no akuma no joi-san (1986), this "making of" offers detailed information and interviews with cameramen, visual effects specialists, and make-up artists. If you've ever wondered what's it like to be on the set of an unapologetic Japanese independent film, this documentary, as well as the Mêkingu obu 'Ginî piggu' (1986), are a rare treat for fans and aspiring special effects artists alike. Are you ready? The doctor is waiting.
