The lone agent in the film is starred by Mason, who has gradually accumulated box office appeal in recent years. Transformers 1 and Transformers 2, which he cooperated with Mai copy, have become the highest films in his personal career, forming a golden alliance with Mason.

Mason, a young student, has the style of Bruce Willis in the bravery of the year. He can be described as the first protagonist of the film. His charm will also ensure the attraction of the film to female audiences. The brave and funny president is starred by black movie star Jamie fox, and Batman girlfriend Rachel McAdams in the Dark Knight plays a female agent, Mason's boss. They will work together inside and outside to rescue him.

A group of well-equipped terrorists occupied the White House, and the super agents alone were ordered to rescue the hijacked president and defend the highest dignity of the United States.

Tatum got a new job as a white house agent, but he didn't expect to encounter a big problem as soon as he took office: taking orders in the face of danger

The white house fell to defend the president. The weapons and ammunition of terrorists were extremely powerful and menacing. The White House was hijacked or shot. The orderly white house was in a moment of chaos. Mason turned into a lone hero and stepped forward to fight terrorists. Throughout the terrorist attacks, explosions were frequent and smoke filled the air. Even the White House, which represents the highest rule of the United States, was destroyed. The picture of cars destroyed and planes killed was almost worthless.

The spark between the agent and the president he needs to protect is the most interesting paragraph of the film. The president played by Jamie fox is not a weak and slender "vase". Since the meeting with Mason, the two have fought side by side. The tactful and courageous president can also operate a rocket launcher when he is interested. Once he fires it, he occasionally shows a few moves without a shadow and gives vent to the terrorists. It is such a pair of good partners of agents and the president who beat back terrorists and defended the American spirit in the contest of great disparity. It is fun to play in this American main melody action film with dog blood still.

This action film, from the beginning of small street fights to the White House, even the president began to go to the sea. Who says that destroying the White House is just a bridge in science fiction? Now action movies do the same.

Emmerich, the old rival of Mai copy, has destroyed the white house twice. Now it's his turn to play Mai copy. The play path of Mai copy is narrow. He has always only played action films and science fiction films. This time, he has returned to his old profession.

Mark used motion capture technology in many scenes when filming the Avengers alliance. American demon God company is undoubtedly the leader in the passive optical motion capture industry. It provides optical motion capture and analysis systems with excellent performance for nearly 1000 users around the world, covering animation production, motion analysis, industrial measurement and control and other fields, but it plays the best in movies, Or Vita digital.

The release of the Lord of the rings 2: two towers shocked the world. Gollum shocked the industry. Such a vivid monster character is unprecedented and one of the most classic action Capture Characters in film history.

Other classic CG characters in the same period include dobby in Harry Potter and Yoda master in Star Wars prequel. However, their influence is not as great as Gulu. One of the reasons is that Gulu is an action capture character and one of the earliest roles using expression capture technology, and is starred by the greatest action capture actor in the world.

Therefore, For Gollum, the two main film technologies he produced on the screen are CG technology and motion (expression) capture technology.

In fact, it's easy to understand that when actors perform on site or in the later special effects studio, they wear action capture clothes and point action capture points on their faces, so that the camera can capture the relative positions of all capture points in space during shooting: the points on their faces are relatively fine, so they are recorded separately with a small camera.

Then, in post production, in fact, it can be directly output on site. The spatial positions of these capture points will be imported into the spatial coordinates of CG and output a skeleton that is the same as the actor's action.

Finally, the CG department will put the finished CG model into the skeleton, re synthesize it in the shooting picture, replace the actor's image, and complete the production of an action capture character.

To make a rough analogy: motion expression capture technology is probably like casting things; First, you have to make a perfect sample, then use the sample to make a mold, and finally pour the metal into the mold to cast the product. Without good samples, where can we get good products?

The old lord of the rings trilogy is the ancestor of motion capture technology and expression capture technology; The technology of making Gollum later became a system, which later appeared in generations of classic films, such as King Kong, Pirates of the Caribbean, the rise of the scarlet ball and so on. The most important point of this system is to endow the actor's performance with virtual roles.

Therefore, actors are very important for motion capture roles. Without a good actor, this virtual role may not succeed.

Gollum, starring Andy serkins, has achieved great success. He plays both Gollum and King Kong.

Gulu's voice is not post processed. It's Andy's own voice on the scene. He once performed Gulu's quarrel with Caesar on a talk show, which is amazing.

How did Andy become a master of motion and expression capture? Yes, it's because of Gulu. The interested audience may notice that Gulu's appearance in the first part of the Lord of the rings is different from that in the second two parts: it can be vaguely seen that Gulu's eyes in the first part are rounder, and then relatively smaller, the shape of the eyebrow Center is also different, and the eyebrow bone is flatter.

The reason is that Peter found that the expression given by Andy to Gulu during the performance can better interpret this role, so he decided to make Gulu look more like Andy.

This may be an important node in the development of expression capture technology.

At the same time, Andy also put on makeup to play the role of Sam, that is, Gollum before deformation.

Andy serkins, a great man, was actually a very famous stage actor in Britain before he entered the cast of the Lord of the rings, especially in physical performance. In the Lord of the rings, he was originally responsible for the physical performance of Gollum, but because of Peter's decision, the expression of the action capture actor was also included in the scope of capture.

Action and expression are the two main elements of Chinese and foreign forms of expression in performing art.

So, when Andy played Gollum, he actually gave his soul to this role very personally. Do you think anyone can play it?

Gollum's actor is no less important than any actor in the film. Even Cameron was surprised. Only then did he think that the technology of making Avatar was mature, which would start the preparation of avatar.

Nowadays, Andy serkins has been recognized as the greatest action capture actor in the world, because he is the player of the earliest action and expression capture character Gollum in the world. He is the master of this system, and even set up a school for training action capture actors; At the same time, he is also a successful action director, director and ordinary actor.

Now mark is shooting the Avengers. Many roles are completed through motion expression capture. Therefore, Andy is the director of motion capture performance.

Unlike hulk and invincible hawk, the first two parts of Hulk in couplet are generated by GC, while couplet is completed by rufaro through action and expression capture, all in front of the green screen.

Some people say that making superhero blockbusters does not require acting skills, which is sheer nonsense. Most of the films are completed in front of the green screen through action and expression capture. The actors have no scene rendering and only have their own imagination. If you have seen the special effects production clips without post-processing, you will feel that they are making blind gestures.

This requirement is actually very high. If the performance is not true, it will inevitably screw up the film.

Many scenes of fierce fighting between iron man and earth are also completed through computer special effects.

Stanley saw stark hanging and pulling around by Weiya, which was extremely low and frustrating. However, after computer processing, he became flying between flying floors and tall buildings, majestic and arrogant. Some fought with the zetatarians in the air.

Stanley said in surprise, "that's how special scenes in the film are handled?"

Mark said, "what do you think? Downey doesn't have super powers. He can't even beat you."

Stanley said, "it's really turning corruption into magic. It's very imaginative."

Mark said: "green screen technology and motion capture technology have reduced production costs and made magic blockbusters and superhero blockbusters mainstream. Now remaking Cleopatra certainly does not need to rebuild a Roman city, even if James Cameron remakes Titanic , we certainly don't need to build an artificial sea and rebuild a ship. The cost of making alien scenes has been greatly reduced. Take a look at this ZetaTalk scene, which is generated by computer. This is a great technology. How sci-fi mysterious your imagination is and how sci-fi mysterious its scene is, which makes the big scene cheap and everywhere. "

Stanley watched Mark show the wonderful clips in the film and said, "it's great. I have a hunch that this is another big selling film."

Mark said, "yes. Remember, there's a result so soon?"

Stanley said: "Jerry's mistress, elandiva, does have some information, but it doesn't work. She pointed out that although Jerry is very careful and never reveals his thoughts, he has a problem. He can talk in his sleep, but he doesn't know it. Elandiva recorded it, but it's nothing important. Gossip is the majority. Maybe the tabloids will be more interested."
