ChampDavSlim The acting is good, and the firecracker script has some excellent ideas.

Allison Davies The film never slows down or bores, plunging from one harrowing sequence to the next.

Payno I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.

Kimball Exactly the movie you think it is, but not the movie you want it to be.

oneofthetwelve Watched the original Men Behind the Sun, and then this sequel. This was English dubbed though. Cantonese version may have been way better. Anyway, from the 1st 2 minutes I felt this is some awkward attempt to ride on the "success" of the first movie.Story about Japanese biological weapons development with some off-topic (maybe I missed something?) autopsies. Some shots are clearly ripped from the first one, like the liquid nitrogen demonstrations and when the leader dude stands in front of the japan flag & his "army". If you haven't seen the original movie, you may like this, anyway I was so much disappointed I recommend watching "Men Behind the Sun" or even "Mermaid in a Manhole" instead, and skip this one.

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.

Ed Cowell He nailed this movie right on the head...I agree with everything he says. I found this movie at the Cleveland Public Library's audiovisual department,and being a lover of foreign horror films,I had to see it. I wound up fast-forwarding past all the talking and watching the nasty bits,which are laughable beyond belief. Of course,if you're not a nutcase like me,this movie may sicken you,but the special effects aren't quite special enough to even do that...

to_live "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 ****
