Twelve wires hanging from the ceiling of the Wannian Yan Emperor, all of which were green, making it easy to erase later. Then, the staff of the special effects team brought a set of wire clothes to help Hu Jun put them on, and then tightly tied the buttons on the wire clothes.

After Hu Jun put on his Wild Clothes, Zhang Ran untied the white belt tied around his waist and tied it around Hu Jun's waist. There was an iron box the size of a lunch box behind the belt. Hu Jun had never seen this thing before, so he said, "What is this thing for?"

Zhang Ran explained: "This is a thruster. The Wannian Yandi is different from Tiangong-1. The cabin is particularly large. For example, our cabin has thousands of square meters. It is very difficult for astronauts to move with their own strength in such a large space. Therefore, each of them will carry a thruster behind them, and after starting it, they can spray gas, allowing astronauts to move freely in the cabin."

Hu Jun suddenly realized: "It's in "Gravity", but they were wearing it in space suits."

Twelve Wias quickly tied to Hu Jun's body, and then the staff pulled Wias and slowly pulled him into the air. At the same time, the camera on the robotic arm was tightly aimed at Hu Jun.

Zhang Ran looked up at Hu Jun and asked, "Old Hu, how do you feel?" Hu Jun smiled and said, "It's okay. I haven't been hanging on the Wild for several years, so I'm a little uncomfortable." Zhang Ran smiled and said, "I think you like space movies very much. Why don't you change your roles and you also play as an astronaut?" In "Full-band Blocking Interference", the only astronaut on the Wannian Yan Emperor was Zhuang Yu, but in the movie, there were many people on the spaceship. Hu Jun waved his hand and said, "I'm old and can't stand the tossing anymore. I'd better play the political commissar!"

Zhang Ran turned around and shouted to the crew, "Camera ready! Wia is ready! Let's try a shot!" Then he said to Hu Jun: "When I shout to start, you can do the swimming movements, but don't be too big, otherwise you will not be wandering in the space, but swimming in the pool!" Hu Jun gestured to Zhang Ran with an OK gesture. Zhang Ran shouted: "Start!"

The on-site staff carefully pulled Wias and slowly moved with Hu Jun. At the same time, Hu Jun also carefully cooperated with Wias' movement and gently stroked forward with his hands.

For any space-themed movie, how to perform weightlessness is crucial and a particularly difficult point. In order to truly show weightlessness in the movie, the directors can be said to have racked their brains and tried their best to do all kinds of ways.

In order to perform weightlessness in "2001 Roaming Space", the great director Kubrick invited an aviation engineer and used a huge sum of $750,000 to build a circular room that was 12 meters high, 2 meters wide and weighed dozens of tons. He fixed a camera in the house. When the actor ran, the footage recorded by the camera looked like the actor was running along the roof.

To this day, there are two conventional methods for showing weightlessness in movies. One is to shoot in real weightless environments. This does not mean that you can actually shoot in space, but there are special planes that can fly at high speed in upward ridges, which can form a complete weightless state for a period of time before and after the top of the parabola. This is how the weightless scene in the film "Apollo 13" was filmed. The crew and actors fly at a high altitude on the KC-135 transport plane provided by Nasa, and can experience about 23 seconds of weightlessness each time, which is enough for the camera to capture certain movements of the actors.

Director Lang Howard spent 612 weightless flights in luxury. During the 612 weightless flights, he successfully shot 234 minutes of weightless time shots. However, this technology is not applicable to "Full-band Blocking Interference". The Wannian Yan Emperor is much larger than the KC-135 transport aircraft. There are many scenes of free cruising in the space capsule, and it is impossible to shoot with the KC-135 transport aircraft.

Another method is to simulate actions, and achieve this "looking" weightless effect under the conventional gravity conditions of the earth. The cheapest way is to shoot under underwater. The resistance effect of water makes people slow and can achieve suspension and flight-like movements in space. However, underwater shooting has defects and cannot truly express the actor's expressions. After all, holding breath and trying to open their eyes are obviously completely different from the performance in a space environment.

After repeated communication with the special effects team, Urshan adopted a method of combining Wia and computer technology. Tiangong Chongcaitte specially designed a control system, which has 12 Wia Si connected to the actors and four points. If it is a simple action, it will be operated by three Wia Si staff members on the other end of Wia Si; complex movements such as random cruising in the cabin will be controlled by the computer, or will be completed by the puppet master and the computer.

After Hu Jun swam out like a fish in the air for more than ten meters, Zhang Ran shouted loudly: "You can stop!"

The staff slowly put Hu Jun down, untie the Wias on his body, and took off the Wias suit.

Zhang Ran asked about Hu Jun's situation, and after confirming that it was fine, he took Hu Jun and the others to the crew command center. Wuershan continued to command the staff on the scene to prepare for the shooting. The technical consultant Yang Liwei had not arrived yet and could not shoot formally, so he had to continue waiting.

The staff turned out the camera I just shot. Not only did the Wiass cut off the picture, but what was even more amazing was that Hu Jun changed his clothes and put on a blue space suit. He slid his hands gently, and it seemed that he was really swimming slowly in space.

Hu Jun and Li Xuejian have participated in many blockbusters and know that this is made through cutouts and synthesis. This is the first time Chen Zhanzhan saw it, and was very surprised: "I changed Teacher Hu Jun's clothes directly. Teacher Zhang, how did this do it?"

Zhang Ran explained with a smile: "We hung the wire to perform, and the clothes on our bodies did not feel weightless, and it looked a bit fake. In order to solve the problem of weightlessness, the special effects team modeled the spacesuits so that the clothes can be synthesized on the actors in the later stages, thereby achieving the effect of weightlessness."

Chen Zhanzhan sighed: "So that's the case, it's so advanced!"

At this moment, Urshan ran in and shouted at Zhang Ran: "Teacher Zhang, Yang Liwei is here!"

After the release of the science fiction film "George" last year, many scientists and astronauts pointed out many omissions and unrealities in the movie. Urshan thought that "Full-band Blocking Interference" would reduce loopholes in this area and strive to be true. In order to achieve this effect, the crew not only invited five technical experts, but also invited Yang Liwei, the first astronaut to enter space in China, to serve as a technical consultant. During the filming, Yang Liwei will assist the actors in simulating weightlessness. However, Yang Liwei is busy with work and cannot stay in the crew for a long time, so he can only take time to guide. Yesterday he had a meeting at the Demon, which was held until very late, and could only come from the Demon City early in the morning.

As soon as Zhang Ran and his party came out of the command center, they saw Yang Liwei wearing military uniforms standing straight. Yang Liwei was not tall, less than 1.7 meters, but he looked particularly energetic. The height of the astronauts should not be too high, because the geometric size in the entire spacecraft cabin is limited, and it is not suitable if it is too high. China's astronauts' height is required to be between 1.60 and 1.72 meters.

"Hello, Director Zhang Ran!" Before Zhang Ran could say hello, Yang Liwei saw Zhang Ran and smiled and said.

"Hello, Mr. Yang Liwei!" Zhang Ran shook hands with Yang Liwei and said with a smile, "It's a great honor to invite you. You are our great hero. The Chinese people's dream of flying in the sky for generations has finally come true to you."

"You are so polite, I am your fan." Yang Liwei chuckled, "I especially like "The Aviator". Not only me, but also the astronauts in our astronauts and scientific research and training center like this movie. They were very excited to hear that I was coming to help with the filming, and they all said, "Oh, China finally has an aerospace movie that can show its face internationally!"

When Yang Liwei arrived, the shooting could begin. The staff quickly tied Wias to Zhang Ran and pulled him into the air. Zhang Ran face down, lay horizontally in the air, gestured twice like Hu Jun and asked, "Is this the action?"

Yang Liwei stood below and corrected: "No, you can't do this in space, and the movement amplitude should not be too large. Many movements in the American movie "Georgement" have a large amplitude, which is wrong. Doing movements in space is very distinctive. If you want to kick out your foot, you have to push your foot forward, which requires a certain amount of force. But once your foot reaches the predetermined position, you must also stop it in time. So once you start adjusting your body, you must give another force to offset it in time and stabilize it in a new body position. You must do all this within a controllable and confident range."

Under Yang Liwei's guidance, Zhang Ran began to practice seriously in the air.

Half an hour later, Zhang Ran basically grasped the characteristics of human movement in space, and the shooting began.

Zhang Ran leaned his hands against his legs, like a fish or like a torpedo, slowly swam forward. After swimming for more than ten meters, he finally swam to the entrance of another cabin. Zhang Ran grabbed the railing of the hatch and pulled it hard, and he flew into the cabin at a faster speed.

Yang Liwei from the monitor immediately told Urshan that Zhang Ran's move was wrong and he was still too hard. Urshan immediately shouted "Stop" and then asked Yang Liwei to go to the scene to guide Zhang Ran.

Zhang Ran had never been on stage to shoot martial arts before, nor did he hang a wire. Now he was hanging in the air to perform, and he had to do movements and his expression was natural. It was indeed a bit difficult. He acted for more than ten times but failed.

Yang Liwei knew that it would be uncomfortable for a person to be hung in the air, so he asked Urshan: "It's been so many times and hasn't passed yet. Aren't you afraid that Zhang Ran will scold you?"

Urshan nodded seriously and said, "Of course I'm afraid! If I shouted this kind of shot that was completely inconsistent with the standards, and if Teacher Zhang saw it later, he would definitely scold me to death!"

The shot was taken until half past eleven. After Urshan carefully checked the camera and confirmed that there was no problem in each link, he stood up straight and shouted: "This shot has passed! Put down Teacher Zhang quickly! The morning shooting ends here, and prepare to put the meal!"

Zhang Ran hung up all morning, and the person was standing sideways for a long time, and his head was a little congested. When he came down, his feet became weak and his eyes were black. He sat directly on the ground. However, when the staff asked what was wrong, he smiled and waved his hand to say that he was fine and just sit down.

Yang Liwei is optimistic about "Full-band Plunger Interference", and now he is looking forward to this movie even more, not only because of the director, big stars, big investment, but more importantly, the crew is rigorous and serious.

After lunch, Zhang Ran and Urshan went to the command center to bring up the shots taken in the morning. He is the producer and every shot of the movie must be reviewed. This is responsible for Urshan and the movie.

After looking carefully twice, Zhang Ran pointed to the monitor and said, "No, my eyes were a little congested in this lens. It should have been hanging for a long time. It was not particularly obvious on the monitor, but it was a problem to put it on the large screen. This lens cannot be done, so it needs to be reshooted."

Urshan stared at the monitor and looked carefully. He was indeed slightly congested and said embarrassedly: "I was negligent!"
