paulgeaf I liked this film. I have seen the first one too and unlike what others have said, I don't think it mattered that much, I still enjoyed both. The worst scenes are not as scary or shocking as I had expected, still, on a par with the first movie so you won't be disappointed! I didn't find the film slow at all, the story was actually quite interesting and filmed with such a macabre/melancholy atmosphere that it worked well. Pity the English dubbed version I watched would have taken away the atmosphere from hearing the original audio track and dialogue. Still, it managed to convey the feeling. I am now going to get the third one and I expect it to be worse than either of the first two as there are only so many ways of telling the same story right...?

Rapeman Laboratory of the Devil is essentially more of a exploitive rip-off / cash-in on the first Men Behind the Sun film. It does include all the gore and nastiness of the original film, but only because it's pretty much a scene-for-scene recreation of it.It is years after the war has ended and the American government have called together all the surviving doctors from Unit 731 to offer them large amounts of money for them to continue their research into biological weapons. From here on out the rest of the film is told via flashbacks concerning the activities of Unit 731 during the war. This time we see the atrocities through the eyes of a young soldier who has been drafted and forced to leave his young wife behind to wait for his return. As he witnesses the treatment of the Chinese and the "experiments'' being carried out, he feels remorse at the crimes of his fellow countrymen and ultimately rebels.The majority of the experiments and tortures on display here are taken as is straight from the first film - we have the hot / cold temperature tests ending in skin flayed from the bone, deliberately infecting subjects with Bubonic Plague, live vivisection, freezing limbs in liquid nitrogen then smashing them, etc, etc. The only major difference here is in the last half hour where the film deteriorates into a melodramatic action flick with Kung-fu and pointless heroics.Due to being pretty much a straight-up exploitation film, Laboratory of the Devil looses the impact of its predecessor. It has goofy "comic relief'' scenes, some nudity, the aforementioned action sequences and an extremely trashy synth score, all of which combine to make it rather hard to take seriously.All things considered though, its not an awful film and if I hadn't recently seen the first MBTS I probably would have dug it a lot more. There's plenty of gore and torture so I'd recommend it to all you rabid gorehound's out there, but if you're looking for a sequel as powerful and shocking as Men Behind the Sun, avoid or check out the excellent Black Sun: The Nanking Massacre by MBTS director TF Mous instead. 6/10

horrorbargainbin I've not seen "Man Behind the Sun" or "Evil Dead Trap" or that many Asian horror films. That said, this movie is more gruesome than almost all European and of course American movies that I have seen. It is not quite as disturbing as "The Untold Story" from Hong Kong. I ran to the computer to make sure the autopsy early in the film was not real. I did not really find anything on the web that proved to me otherwise. The naked girl does not look like a dummy and the dry limbs being sawed off, that's shocking. I'm not sure that if it was a real corpse, that it was then material taken from stock footage. Anyway, it blows away the first film in the "Guinea Pig" series, which has a very low budget and poor production values. This movie has a large cast and does not skimp on special effects. All the gun deaths result in blood splatter. In more lazy gore films they sometimes don't bother and you get a silly PG moment. The first half of the film is heavy and serious and I was afraid each upcoming scene would make me squirm. Then the movie becomes over-dramatic and unrealistic with scenes that bring to mind "The Story of Ricky". This is an exploitation film more than a movie trying to make a statement about history. The end will have you laughing and perhaps will help ease the guilty brought on by enjoying earlier scenes of gore that are based on real human death camps. Recommended.

hempgrindhead 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.
