Men Behind the Sun 1 (1988)

Option 1Can't Watch?

Wait 30secs. Movie still not playing? Click the "Can't Watch?" tab.

If the movie didn't load, it means you are being blocked by a security service we use. This can happen for a number of reasons.

Click this first

A new tab will open and a basic security check like a captcha will be performed. After completing the check, close that page and return here.

Refresh this page. Wait 30 secs. The movie should load and you can just hit play.



If it still doesn't play, Click here to watch the movie

The movie should now start playing in a new tab of your browser or begin downloading to your device. This option has the minor disadvantage that English-language movies with optional subtitles in the movie player will not include these subs with this method.

The new system here has been designed keeping in mind even people with low internet speeds sub-8mbps. Even if you have a really bad connection, you should still be able to watch the movie without any issues if you:
Start the movie. Pause it. Wait for 30-45 seconds. Start playing again.

This 'Can't Watch' method really only works if it's your specific device/browser that's interfering with the player. There is no real advantage of speed here. Or if there is a temp network glitch or read lag from the server disk.

If you're still having problems, try using 'Incognito mode' in your browser. On iPhones, especially older ones, use Chrome instead of Safari. Might help.

IMPORTANT: Please make sure that the newly opened tab is not an ad popup asking you to download some software or whatever. Close any such popups and don't download any software - those are ads. Nothing is needed to be done by you other than to complete the security check which is often automated.

The subs are a bit off here and there – was already burnt into the video, so nothing could be done

AKA: Hei Tai Yang 731, Black Sun 731, Squadron 731
Year: 1988
Directed by: Tun Fei Mou
Starring: Gang Wang (Lt. Gen. Ishii)
Country: Hong Kong, Asian Cinema
Language: Mandarin (English subtitles)
Runtime: 01:44:58
Genres: Military, Based on a True Story, Violence Against-Relationships with Animals, Captivity, Gruesome, Fascism, Torture, Racism, Medical

Plot – Spoilers:
Men Behind the Sun is based on Unit 731, a facility run by the Japanese during WW2, where experiments were conducted on mostly Chinese and some Soviet prisoners. The prisoners were referred to as ‘logs’ and the experiments were part of a grand plan to design biological weapons.

Lt. Gen. Ishii arrives at Unit 731 with a reputation that forces even the Generals there to be servile, with his every whim unquestioned. Coinciding with his arrival, a squadron of teenage boys are brought in, who act as a sort of mirror to the atrocities that the perpetrators rarely stare into. With defeat for Imperial Japan looming, Ishii believes his Unit is a secret ace that can turn the war around and the experiments get more brutal.

Apart from the quite vivid human torment, Men Behind the Sun also includes a few controversial scenes of violence vs animals such as a cat being devoured by rats (later claimed by the Director to be fake), and an (oddly) aesthetic scene of rats on fire scurrying hither thither.

Predictably, the movie was received with outrage and was promptly banned in a number of countries though most of this probably had to do with its historical context.

I watched an English dubbed version which had a shorter running time by 4 minutes but not sure what was missed out if anything. Historical accuracy hmmm dubious, its CAT 3 exploitation FFS.
Mostly just people in uniform being people in uniform interspersed with some grisly-fun. Women gets the skin ripped from her hands, man prolapses his whole intenstine and admin is right the flaming rats were quite artistic.
At least they destroyed everything in the end. The UK is still destroying the mustard gas canisters from WW1 so you have to wonder what else is still hanging around at Porton Down.

Incredible film! Since the Japanese government downplayed the film as anti-Japanese propaganda and exploitation, we can assume that this film is very accurate. It shows what can happen when megalomaniacs with unlimited power try to be God. There is a scene where Lt. Gen. Ishii is proudly telling his comrades that he has come up with a virus that can kill the entire world’s population and they all applaud like it is a great idea. It’s disturbing to say the least. 5 stars.

I haven’t seen the 3 other “Men Behind The Sun” films yet but either this one or one of the other 3 will be in my “Old Mother Hubbard’s Top 100 Movies On EUM” list.

Great movie outside of the Dub being in Chinese… Philosophy of a knife I feel was a bit better at explaining why they where attempting the experiments in the first place.

Eu lembrei como disse alguém nos comentários esse filme estava disponível em vhs nos anos 90 com capa bem curiosa mostrando os experimentos graças a internet consigui matar a curiosidade mas descobri que e um filme não um documentário filmado o que seria mais aterrador como nós filmes nazistas

This movie so good because based on a true story which makes it historically accurate.

You can learn things about what actually happened by watching this historically accurate Hong Kong CAT.III movie.

Every event that occurred in this movie actually happened exactly as filmed.

History can’t change whether you like it or not. You can’t change what happened in the past. It is not racist to read about or learn history or watching movies/documentaries based on history. Learning history isn’t inherently racist because history is about studying the past to understand how societies, cultures, and events have shaped the world we live in today. The purpose of learning history is to gain knowledge, perspective, and insight into the complexity of human experience, not to promote or perpetuate racist ideologies. History is full of pain and negative events and the truth hurts and sucks! This movie is based on a true story and it DID happen whether you wanna believe it or not.

The message of this film is no matter what you do to Asians, there is still billion of them around.

Is this the same as Secret Prison Part 1 (2010) and Secret Prison Part 2 (2010) just posted under a different name which also covered the atrocities of Unit 731?

Aside from the animal cruelty in this film, the biggest thing that really pisses me off is the fact that some of these sick fucks never stepped into a courtroom to face justice for war crimes but were given immunity and sanctuary in the U.S. just like the Nazis before them. Makes me sick really. Honestly, I wouldn’t be surprised if Saddam Hussein and Osama Bin Laden are having drinks together and exchanging war crimes stories in some deep underground military base in the U.S.

Its no secret that the Japs were one of the cruellest regimes during WW2 and other conflicts as this film points out. Seeing as this is based on fact rather than fiction puts a whole new perspective on things. I think this film is quite accurate as to the atrocities the Japs perpetrated, and its no wonder they were nuked twice in 1945. Not an enjoyable movie but one that is necessary to bring out the truth of war.
