When making a movie, directors and producers will always try to make sure the finished product is perfect. But like other professions, they also face many problems in the production process, and sometimes solving them can change the entire film industry.
Watch blockbuster movies in post-production – from Avengers to Mad Max, scenes mostly use green backdrops for VFX scenes. But why green? Absolutely for a reason!
Blue is used intentionally, as this is a color that will not match the natural color of the actor’s hair, skin, and eyes . In the case of actors with green eyes, they will use a blue screen.
Of course, with such a feat, accessories and clothes must not be used in blue. As a result, post-processing will be faster and simpler.
Since Avatar, the world of cinema has been flooded with movies in 3D format. But there is a fact you will not realize, that 3D movies today help you have a much more comfortable experience than before.
Previous 3D movies used to abuse the effect of flying objects towards the viewer. The problem is that our brain will not interpret the image as an illusion, but react as if it were real. When overusing this effect, viewers may have to receive some bad effects: eyestrain, dizziness, headache, nausea.
So later on, the effect experts accelerated the speed of the object, so that the brain did not have time to focus on it. Or, they do 3D effects with small objects (sand, dust, snow), so that the brain does not focus on that.
Most horror movies feature children, and the child actor often doesn’t know what kind of movie he’s acting for. Scenes are rarely done in chronological order, so it’s hard for a child to get a complete picture of the movie.
Plus, there’s nothing really scary on set. The devil is thanks to post-production techniques, sound, music… also.
A trailer is a short introduction to a movie, usually about 2 minutes long. Logically speaking, the film company would be responsible for making it, because it would be easier and less expensive. But not! For the most part, they will hire advertising agencies, and they absolutely have a reason to do so.
The truth is, not all film companies are good at marketing, and it’s hard for them to understand the best way to attract viewers before they hit theaters. So many companies decide to hire advertising professionals, instead of saving a little money and causing the film to fail.
Scenes with mirrors always have to be carefully calculated, placed at a special angle, so that the mirror only reflects the actor but ignores the camera and light.
For example, in Terminator 2, there’s a scene where Linda Hamilton’s character tries to take away the chip in “Terminator ” played by Arnold Schwarzenegger. In fact, this scene has no mirrors at all. Arnold sits opposite the camera, and the other nape is actually a dummy.
A lot of movies – even blockbusters – have “grits”, and even very large grit. For example, in The Dark Knight Rises of the Batman series, the Batman guy has a scene going into the tunnel in the middle of the day, but when he comes out the other side, it’s dark.
But you know what, directors are sometimes so perfectly clear that a movie has grit, and they even leave it behind on purpose. In the case of Batman, this guy looks more impressive and “genuine” when appearing at night, and director Christopher Nolan just needs to be enough. Moreover, the filmmakers also believe that the audience will focus on the story being told, instead of the “silly” details.
Most of the snow in Hollywood movies is man-made, and most of it is supplied by a company called Snow Business. This company was founded in 1983, and is capable of making 200 different styles of snow.
But why not use real snow? The reason is because they are too difficult to control, can melt at any time and easily spoil the scene. However, there are also some movies shot in real snow, like The Revenant – the movie that brought Leonardo Dicaprio’s first Oscar gold statue was shot at a ski resort in Canada.
Mass actors – especially roles in the auditorium have very strict requirements. They will not be able to look directly into the camera to create a natural feeling, and may even be kicked out of the set if violated. Besides, they are also not allowed to wear clothes that are too prominent because it will distract the audience from the main character in the scene.
The majority of scenes show that food – especially parties – is not edible. The reason is easy to understand: real food doesn’t last long, and movies can’t be shot in just one day!
For example, the party scene in Harry Potter for example! Only the first part of the movie uses real food. From part 2, most of the dishes are made from turpentine.
