We can list many categories of films. However, despite their category, the general outline of the production of each looks the same. The case is different in a documentary film. This is a special kind of film. Of course, just like any other kind of film, a documentary film requires proper preparation, organisation, then the shooting of the material, and finally the editing. However, in order for a documentary to remain a documentary, there are certain rules that must be observed, which define a film as a documentary. First and foremost, documentaries present a slice of real, actual reality. Unlike other films, it must not be subject to interference from the director. As we know, the director has a very important, even crucial role in the production of any film. However, with a documentary his role is very truncated. After all, it is supposed to be a piece of the real world, problems, authentic images, stories and facts. Here, the scriptwriter is life and time. So where is this limit of the director's possibilities? What can he afford to do? To what extent can he guide the cinematographer and the characters? How strongly can he provoke situations so that it is still a documentary?
