A really nasty 'atrocity' film from Hong Kong, looking at Japanese biological experiments on the Chinese during WW2 and the infamous Unit 731 in particular. It's a low budget film but quite expansive in tone, giving a good picture of the international backdrop to the events portrayed, but the emphasis is very much on the blood and gore taking place at the facility and even the characters come second to that. It's an ultra disturbing film, one of the most disturbing I've ever seen, up there with the likes of CANNIBAL HOLOCAUST in terms of on-screen content; it doesn't help that some of the corpses shown were real and one moment of animal violence is particularly queasy. Sure, I get that the director wanted to tell the truth and make this as realistic as possible...but only strong stomachs need apply here.

I saw this for the first time recently n got disturbed badly. I cudnt sleep or do my workout.

This movie is not supposed to be enjoyed nor shud be viewed for entertainment values. It shud be only seen for sheer enlightening.

The autopsy of an alive child made me lose hope in humanity. The gruesome experiment in the decompression chamber took away my sleep n appetite.

The most shocking aspect is why wud anyone protect a monster like Shiro Ishii. For scientific data?

T.F.Mous' 1987 film "Man Behind the Sun" has to be one of the most disturbing and unpleasant movies ever made.It tells us about the atrocities committed by Japanese scientist during the Second World War in China.The acting is pretty good and I think that some of the actors did an outstanding job.The film offers also some of the most revolting gore I have ever seen.Some scenes are truly sickening for example a man is put into decompression chamber and the pressure is steadily increased until he shoots intestines out of his anus-actually Mous used a real corpse to make this scene.There is also incredibly graphic autopsy of a young mute boy-a real cadaver was used for this sequence as well.The scene where a real cat is attacked and consumed by literally thousands of starving rats is incredibly vile and unnecessary.Overall,"Man Behind the Sun" is pretty hard to find,but if you liked "Cannibal Holocaust" or "Bunman:The Untold Story",then give it a look.However fans of cute American horror should avoid it like the plague!
