The first Men Behind the Sun marked the beginning of the Category III (CAT III) movies, the extreme graphic violence and the historical theme made Men Behind the sun going to the highlights, apparently, it grossed enough money for make a "sequel".Men Behind the sun II is directed by Godfrey Ho (remember Ninja Thunderbolt ? Ninja Terminator ?), the greatest Hong Kong B-movie director.This is more a remake than a sequel, with the only difference is that we don't see the cadet's "point of view".Men Behind the Sun II is the most violent and nasty (at least in my opinion) of the whole Man Behind the sun Quadrilogy, it includes the most disgusting autopsy scene ever filmed.The special effects are realistic, shocking and gross.The English dub is cheesy.Many people complained at the time that T.F Mou made Men Behind the Sun just for make some cash on this sad story, actually, i think that the guy who did this is Godfrey Ho, compare the original with this sequel/remake, you will notice that there is something "lacking": the historical content and the philosophy and the message.

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.

"Man Behind the Sun 2" aka "Camp 731: Laboratory of the Devil" is one of the most worthless films I have ever had the displeasure of seeing. Godfrey Ho (who is incorrectly listed as being an alias for T.F. Mous) managed to take Mous' disturbingly realistic film (which was originally intended to be a documentary and ended up falling somewhere in between docudrama and exploitation stomach turner) and completely flush out every element that made "Man Behind the Sun" so hard to view.What's worse is that Ho doesn't even make a weak attempt at a plot. Instead he literally copies Mous' work word for word only stopping to pump up the amount of blood, torn flesh, innards, and severed limbs. Ho never treats his victims with honor, rather he goes out of his way to completely exploit the unwatchable torture and mass executions these innocent prisoners of war endured.Though, the most grueling ordeal is having to sit through a film that is based on real documentations of Camp 731, which was set up in Harbin, China by the Japanese during World War II. Inside Camp 731's Nazi-like interiorcaptured Chinese, Koreans, and Russians were subjected to inhuman biological warfare testing. In the end out of 3,000 men, women, children, and infant prisoners not one was left alive and some 200,000 more Chinese died from neighboring areas when the camp was imploded and the Black Plague (which was being experimented with) was unleashed.Godfrey Ho should live in shame.Zero Star Rating out of ****

I wouldn't call this a horror movie, it is more like a very violent drama...The gore scenes are great, even if the autopsy and amputation scenes are by far the most detailed and violent. The plot is better than most of the movies I've seen, and the movie is very well-directed...Still, to be honest, I think this movie would have been even better if there were more autopsy scenes, since you watch this movie for the gore!However, I guess I have to give this movie 10/10, cause the scenes you have heard people talk about is twice as cruel as you could imagine...watch it, and enjoy the violence!!!!!!!!!!
