9 secrets of filmmakers that the audience does not know

In the process of making a film, the directors and producers faced many problems to ensure that the finished product was perfect. And sometimes solving them can change the entire film industry.

1. Why is CGI wallpaper blue?

The fact that filmmakers mostly use green backdrops for special effects is justified. Because this is a color that will almost not match the natural color of the actor's eyes, hair and skin. They will use a blue screen if the actor has green eyes.

Of course, in these scenes, the accessories and clothes are also not using blue to make post-processing quicker and simpler.

2. 3D movies in the past were actually annoying

Currently, films in 3D are appearing more and more. But one reality is hard for audiences to recognize, that today's 3D movies offer a much more comfortable experience than before.

In the past, 3D movies were very abusing the effect of objects flying towards the viewer. This causes our brain to react as if it were real and can cause some negative effects such as eye strain, dizziness, headache, and nausea.

To overcome this, the effect experts have accelerated the speed of flying objects or 3D effects with small objects (sand, dust, snow) so that the brain does not focus on it.

3. Children in horror movies often do not know what they are doing

In horror movies, child actors (if any) often don't know what they're doing because scenes often rarely follow sequences and there's nothing scary on the set. was created using behind-the-scenes effects.

4. Movie trailers are usually made by advertising companies

The trailer is a short video, about 2 minutes of introducing a movie. Most film companies will hire advertising companies to make trailers because not all filmmakers are good at marketing and know what is the best way to get viewers before they hit the theaters.

5. A mirror shot is the hardest

Mirror scenes are always the most difficult, because they have to be carefully calculated so that the mirror only reflects the actors, and the camera and the light do not.

6. The intentional "grain"

Many movies - including blockbusters - have "grit" and directors sometimes know that, even if they intentionally leave it behind.

For example, in The Dark Knight Rises of the Batman series, there was a picture of Batman walking into the tunnel during the daytime, but it was dark when he got out of the other side. Director Christopher Nolan knows this 'hotel' well and he 'ignored' it because obviously the guy Batman looks more impressive and "better" when appearing at night.

7. There is a company specializing in snow making for Hollywood

Snow Business, a company founded in 1983 that provides artificial snow for most Hollywood movies. This company has the ability to create 200 different types of snow.

8. Mass actors must never look at the camera

There are very strict requirements about the public actors, they must not look directly into the lens to create a natural feeling and not wear clothes that are too prominent because it will distract the audience from the main character in scene.

9. The food in the movie is rarely genuine

The food didn't last long, and the movie couldn't be finished in just one day. Therefore, the majority of food that appears in scenes is not edible.

For example, in the party scene in Harry Potter, real food is only used in the first part of the movie, from part 2, most dishes are made from rosin.
