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 »

More guts, no glory, no story., 7 February 2001
Author: to_live from Normal, Il

"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 interior

captured 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.
