Why are all interrogation rooms equipped with exhaust fans in TV series?

In the underground front struggle of that era, secrecy was a very important principle. In this regard, Scout and Zhongtong both suffered a lot. For example, Qian Zhuangfei, one of the "Three Heroes of Longtan", became the confidential secretary of Zhongtong spy chief, intercepted the top secret telegram sent by Wuhan Zhongtong Commissioner, and rushed to Shanghai to report to the police in time, successfully avoiding and reducing the great harm caused by Gu rebellion. After the victory of the Anti-Japanese War, the military system was reduced to the "Secrecy Bureau".

The Kuomintang secret service, whether military or central, handles cases differently from ordinary police stations. They don't handle ordinary criminal cases, but all the people detained for trial are "political prisoners". These two secret service organizations have been engaged in illegal "secret service rule" since they infiltrated the open judicial organs of the National Government in the 1930s. They can arrest, detain, interrogate and even kill political prisoners without evidence or legal procedures. Many things are shameful.

Therefore, the above two factors prompted the secret service to set up many secret prisons and secret interrogation rooms, especially the interrogation rooms were mostly built underground or semi-underground, in order to avoid information leakage or the cruel torture methods used by them. These interrogation rooms have almost no windows and the air circulation is very bad. If you don't install an exhaust fan, let alone interrogators, the executives will be unbearable at first. In his memoirs, Shen Zui, a former scout spy, described how the scout interrogated the arrested underground party member in Zhazidong and Baigongguan. The cruelty of his methods exceeded our imagination today.

The thick blood gas, the burnt skin of the soldering iron and the smoke of spies are shrouded in the narrow interrogation room, so the interrogation room needs an exhaust fan. Lu Hanqing's experience in the TV series Kite is by no means exaggerated. The military's method of interrogating political prisoners can be defined as cruelty. Many of them are senior spies, and even Dai Li himself has presided over the design of Chongqing military interrogation room and the trial of major cases. Under all kinds of corporal punishment, there are unyielding and, of course, rebellious.

There are too many similarities in TV spy war dramas. Installing only an exhaust fan in a closed interrogation room has another meaning, which is to create a gloomy atmosphere and deliberately exaggerate the suspicion of violence and blood. The author used to like watching spy movies, but every time such a scene is fast forward, because it is meaningless to the plot.

Anti-war dramas are so popular now, many people must have seen one or two such dramas. In these plays, there are often some spy interrogation institutions. If you are a careful friend, you should have found that each of these interrogation rooms is equipped with an exhaust fan. Why do you want to install this thing? Its function actually has several points.

First, breathe. As we all know, these people who can be caught in the interrogation room are all useful people. And once these people are caught, there will be accomplices to save them. So in order to prevent these people from being easily rescued, they will naturally be taken to a relatively remote place for trial. Therefore, interrogation rooms are usually built underground, which will be very secret and will not be discovered. But there is a disadvantage of building underground, that is, ventilation will be a problem. There is no ventilation in the underground, so it will be uncomfortable to stay in the interrogation room. These interrogators just want to make the prisoners suffer, not themselves. So they had to build a vent to let the air circulate and let the officers who stayed below breathe fresh air and have a comfortable environment.

Second, set off the atmosphere. A dark place like an interrogation room can make people feel very depressed. But when a beam of light comes in, it will leave people with hope. During the trial, if the prisoner completely loses hope, then he will become fearless, which is not a good thing for the trial. And if there is light in it, just like a beam of light in the dark, it brings hope and will keep the prisoner from giving up completely. They will have expectations and desires for life. Interrogating them at this time may have unexpected results. Therefore, this ventilator will also have a contrasting atmosphere and create a feeling of hope.

Third, it is more convenient to shoot TV series. If the interrogation room is completely black, it will be inconvenient to shoot during the filming process. And if a beam of light comes in, it will be more convenient to shoot with a bright spot. Furthermore, it is also necessary to consider the viewing effect of the audience. In the dark interrogation room, the audience was depressed and had a bad feeling. But when a beam of light shines into the interrogation room, there is a mysterious and solemn feeling. In this way, when the audience is watching, their mood will not be greatly affected, and they will feel very comfortable when watching the drama.

To sum up, it is also necessary to equip the interrogation room with ventilation fans. The function of this thing is still quite big, it can set off the atmosphere, exhaust and ventilate.

Let's put some real photos of the Kuomintang military prison and concentration camp first, so that everyone can understand the atmosphere at the scene.

It can be seen that darkness is the main color, and remote geography (for confidentiality), thick walls (to prevent prison break), lack of sunlight (to deepen the fear of detainees) and sometimes even being underground (for sound insulation) are essential elements. Groups of revolutionaries suffered physical and psychological devastation here. Some of them sacrificed and kept their ideals and beliefs, while others endured hardships and betrayed their organizations and beliefs.

In modern TV series, there are some such effects: the stills above have no lighting effect, so it is difficult to set off the atmosphere, and they are all bad reviews.

In TV series, such heroes usually need to be backlit into a firm silhouette at such a sad moment, which conforms to their identity and psychological activities, has a lofty and sacred sense of ceremony, and finally sublimates their emotions. If this kind of backlight comes from the exhaust fan and rotates slowly, it will cover the protagonist with a touching fine light and shadow, and at the same time it will bring a little dizziness to the audience, and it will certainly be better to add a little religious color. If we can skillfully use the sunlight outside the exhaust fan (which can be a false light source) to form an obvious contrast effect with the darkness in the room, thus setting off the contrast between the hero's heart and fate and creating a strong dramatic conflict, this is the highest application of the "exhaust fan effect".

The picture above is a passing work.

In many film and television dramas, we will see such a picture: the narrow interrogation room is dark, drums are bursting, and a small exhaust fan creaks and turns behind. Someone asked, why should the interrogation room be equipped with an exhaust fan? What's the use?

In fact, this is to set off the gloomy atmosphere of the interrogation room, let the audience enter the play, and have an immersive feeling. In the damp and dark interrogation room, a beam of light passes through a small exhaust fan. The light is looming, and with the strange BGM, it scares you through the screen. A small exhaust fan brought the audience into the play in an instant.

Some people make fun of it. This is because Hengdian has only one interrogation room. It happened that an exhaust fan was installed in this interrogation room. Therefore, this exhaust fan has appeared in many film and television dramas. The mountain is still this mountain, the water is still this water and the exhaust fan is still this exhaust fan. In order to give you an immersive feeling, film and television dramas have also tried their best. After watching the play, you might as well observe it. What are the familiar formulas and familiar details?

This is just to set off the atmosphere. Photographers all know that installing this sector in front of the light can create various lighting effects when rotating! That's all! ! !

By the way, this technique was introduced from Hollywood blockbusters! Don't believe you saw this thing in the movies of the fifties and sixties?

I deliberately looked at the answers of other respondents and found that there was no answer I wanted to answer. It depends on your answer that it happened by accident, and some said it was a psychological effect. In fact, I feel that it is inevitable that this kind of exhaust device will become the standard of interrogation room after it comes out. Mainly its function, exhaust and odor removal. Interrogators are human beings. When he was tortured, the shit of interrogators and the shit of people scalded by iron didn't smell good. There was no exhaust fan in ancient times, so there was no way. When this thing was invented, it may have been used in the first place.

Of course, the strange effect of light on film and television dramas is inadvertently obtained after installation, perhaps only in film and television dramas. However, its exhaust deodorization effect is the most basic.

Landscape teachers should create a sense of sacrifice and learn the atmosphere of Christian church. The light shone on the victims from behind, and the sense of sacredness suddenly came out of generate. Later, more people followed suit and gradually became a little out of shape. The first consideration of a real interrogation room is confidentiality. There are no windows and certainly no exhaust fans. Film and television drama works are works of art, and the feelings of ordinary audiences should be considered, followed by authenticity.

This is not always the case in practice, but most TV dramas are like this, which shows that most directors and scenes are taught by the same teacher and graduated from the same school!

Never been there. Guess. That place is not peaceful, and there are all kinds of instruments of torture. Make the prisoner bloody and burn the stove with a cannon. The air inside is extremely turbid.

As a filmmaker, to tell you the truth. The so-called exhaust fan is just a prop for light and shadow effects here. If you look closely, you will find that every time this lens comes in, a beam of light will come in from the outside, and the blades must move very slowly to create a dynamic sense of light and shadow. There must be prop smoke in the indoor air to give the light a three-dimensional feeling. The reason why it is used in interrogation room is that this kind of lighting effect is mostly used in darkroom, and interrogation room conforms to this atmosphere.
