Did You Know?

The uncut version was originally refused classification by the OFLC in Australia in September of 1992. One month later, the film was resubmitted, only heavily cut. It received an R18+ rating for cinema release, but when the heavily cut version was resubmitted for a video rating in 1994, it was again refused classification and banned in Australia, even though the same print was given a cinema rating. Finally, in 2004, the film was resubmitted and received an R18+ rating for the original uncut print on video.See more »

super sick remake of men behind the sun, kind of., 11 October 2002
Author: hempgrindhead from la, ca

I honestly don't understand how someone could like Men Behind the Sun but not like this film. Although inferior in some ways, it is extremely devastating. We are treated to brutal extended autopsy, Arms being stripped of flesh,an autopsy on a living guy that looks suspiciously real(they remove his heart as it beats and when they cut him open it bleeds for real, exuding out of the fat and tissue layers)decapitation, dismemberment and more. I have read reviews for Guinea Pig:devils experiment wherein the reviewer states that he believed it to be real snuff, come on now.This flick has more realistic slaughter than the first Guinea Pig. This film uses real corpses for all the effects and the living autopsy scene is brutal. the only way i figure they did it without actually killing a guy is if they filmed a heart surgery or cleverly slaughtered a pig disguising it as a human. Don't believe the bad reviews. This movie is sick and deserves more credit.
