There are not many pre-earthquake location scenes in "Tangshan Earthquake", many big scenes can only be CG in the post-stage, and only the place where Yuan Ni lives has built a corner of the city...

After the filming of the location scene, it is necessary to tear down the entire scenic spot, arrange it in the state after the earthquake, and start filming the scene after the earthquake.

How do you represent an earthquake?

Zhang Junsheng and Brad Peyton, including the rest of the crew, initially planned to use the method of blasting, but after experiments, it was found that the state of the blasting was different from the collapse effect caused by the earthquake, and finally the crew chose to demolish the building partially, but the building where the protagonist's home was located needed to show the entire collapse process, which could only be completed by blasting.

In order to make the state of the house after the collapse as close to the real state after the earthquake, the crew did not let the excavator directly knock down the house, but tied ropes to the wall and pulled the house down through mechanical pull.

This gives you a result that is closer to the real seismic state...

The master of the construction company was busy all day before the houses in the entire shooting area were pulled down and arranged to look like after the earthquake.

Now only the protagonist is left, and the building where their home is located still retains its original appearance.

The collapse of the protagonist's house is a close-up scene in the movie, and the process of collapse needs to be shown, first using blasting to complete the collapse of the building, and then correcting it through computer special effects in the later stage, so that the effect looks like it is collapsing...

As for Zhang Zifeng being pressed under the steel plate, this shot must be fake...

In the later stage of synthesis, Zhang Zifeng only needs to put on makeup, lie on the ground and make a shot that is pressed by the steel plate, and in the later stage, the steel plate and other objects are added through special effects, and the effect of the synthesizer being smashed...

Of course, these all take time, and it is impossible to show it directly to the director as soon as possible, so the special effects and the group refer to the fact that there is a special draftsman on the scene of the crew, as long as the director needs it, tell him to draw me a steel plate that is pressed by the steel plate, and he will draw it into the director's request, if the director thinks it is feasible, he will immediately send the image to the special effects team, and the special effects will be rendered, synthesized and other operations, and finally the image will be completed...

The pyrotechnician is from Brad Peyton's team, and they were in charge of the pyrotechnics for 2012 before, and they were very good!

In fact, there are also pyrotechnics in China, and Bayi Studios is best at pyrotechnics.

But, to be honest, the pyrotechnic industry in the mainland is not very standardized!

There are qualified pyrotechnics in the country, six Bayi Factory, four Shanghai Film Studio... Responsibly, no more than fifty nationwide.

Fifty professional pyrotechnicians are faced with an annual output of 15,000 episodes of TV dramas and an annual output of four or five hundred films.

One can imagine how many fake pyrotechnics will be circulating in this market.

Zhang Junsheng is not short of money, and he doesn't want accidents!

Pyrotechnics are the most problematic!

The year before last, a fake shell exploded during the filming of a war scene in "My Regiment, My Regiment", and Guo Yan, the leader of the pyrotechnic group, was unfortunately killed...

"I Have a Date with Spring", Yu Haoming and Ren Jiaxuan were burned, because the crew's safety measures were not perfect, and the pyrotechnician's skills were not in place!

Human life is at stake!

It's really not that Director Zhang doesn't support domestic production...

……

The crew of the second film crew rushed over, and they also wanted to learn about Hollywood blasting techniques...

Zhang Junsheng smiled and didn't say anything, it's normal for directors to be studious!

At about half past ten, Zhang Junsheng picked up the megaphone and shouted: "In the last fifteen minutes, everyone retreats to a safe distance!"

Except for the blasting team, which was doing the final checks, the rest of the workers retreated to the safety line.

Soon, Brad Peyton came over to report to Zhang Junsheng that the demolition team was ready!

"Just a final confirmation, has everyone exited the safe distance?"

No one spoke, and the scene notes began to count down: "... 3, 2, 1!

"Boom!"

There was a muffled sound, and the ground shook slightly.

Everyone turned their attention to the direction of the source of the sound, and the department store building surrounded by a blocking net emitted billowing smoke and dust, and at the same time, the building was like dominoes, a chain reaction.

In eight seconds, the entire building was in ruins, and then the dust that obscured the sky and the sun scattered from the ruins...

At the same time, the sprinkler truck, which had been on standby for a long time, was working at full speed to sprinkle water and reduce dust.

The whole process lasted about five minutes, and when the smoke and dust cleared, Zhang Junsheng hurriedly walked behind the monitor and looked, the shot was very good!

It's just that the shot just now was blasted, and it had to be modified in the later stage to change it to an earthquake collapse!

"Attention all teams, the group performance is on the stage, and the aerial photography is ready!"

How to show the tragic situation?

Aerial photography through long lenses, of course...

This needs to be performed with a group performance with a lot of clothes...

……

"Director, will we be scolded for being so focused?"

At the end of the day's shooting, Guo Fan suddenly thought of something and asked Zhang Junsheng.

The filming after that mainly focused on the relief of the People's Liberation Army at the risk of aftershocks, and of course, Zhang Zifeng was trapped under the stone slab and stayed strong for three days...

“… There is no main theme, after the Tangshan earthquake, did the People's Liberation Army rush to the scene as soon as possible? Let's shoot according to the recorded information, what are we afraid of?"

The PLA is always the cutest person!

According to the record of the Great Earthquake, a unit was stationed in the gymnasium at that time, and after the earthquake, the water pipeline was paralyzed, and the victims had difficulty drinking water, and drinking water rationing was required. The People's Liberation Army (PLA) drank water from the swimming pool in the stadium and gave all the drinking water to the victims.

After the earthquake ended, the People's Liberation Army began to evacuate, and when the troops left, the citizens of Tangshan spontaneously organized a farewell and stuffed food into the arms of the People's Liberation Army.

The 38th Army will always be the loveliest person in the hearts of Tangshan people.

Sighing, Zhang Junsheng spoke: "In fact, in China, as long as it comes to the main theme, even if what you say is really what happened, someone will scold you, don't worry about them..."

There is a group of people who know how the United States is free and democratic at every turn, but they don't know that the patriotic education of the United States is better than that of China, and a group of people gather together to shout 'USA!USA!'

Guo Fan nodded, and Zhang Junsheng continued: "Okay, don't think so much, although the script is not perfect, it is definitely not a matter of the main theme, but many things that we can't touch, such as the smashing and looting during the earthquake, can we shoot head-on? Definitely not!"

"Hurry up and go back and have a good rest, I'm going to shoot a rain scene tomorrow!"

It's March, and the weather is definitely not hot, but the movie reflects the events of July, and the actors need to wear pants and vests to shoot rain scenes, and it will be very cold when the rain pours on them, so the rain scenes must be filmed as soon as possible...

The medical team of the crew must observe more, and there must be no large-scale cold!
