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 »

It has got guts...literally, 5 November 2004
Author: Coventry from the Draconian Swamp of Unholy Souls

Even though I swore to myself I would never lay eyes again on 'Men behind the Sun' or any of its sequels, I am now reviewing part 2. Go figure! I guess the call of the extremes just was too irresistible. At least now I clearly recall why I took this pledge…. These films are almost unbearable. The 'Men behind the Sun' franchise might as well be the most controversial and shocking series of films ever made (maybe a tie with the 'Guinea Pig' series, though) and handles about despicably explicit experiments performed on prisoners in a Japanese army base during WWII. These unfriendly Japs are developing germ-bombs to disable their enemies and a whole lot of other sick stuff involving nitroglycerine etc… There's an ultra-thin wraparound story about a young soldier who's sent to serve in the camp against his will but that's of minor importance. This second chapter is less repulsive than the original, but still contains more than enough sequences to make your stomach turn. Luckily the make-up effects are often cheesy and unquestionably fake. The acting is weak and the directing (by Hong Kong B-movie legend Ho) is atrocious. This is a film without any values. The only reason why it is made is because the DVD looks good in a cult-collection like mine.
