The main difference is the platform on which the film is published. A TV movie, of course, has a limited time frame on the air, but it is in no way inferior to a traditional documentary, which is published, for example, on a YouTube channel. In a documentary film, the degree of author involvement in the narrative is greater than in a television film. But the main function of the narrator in both screen works is to form the viewer's idea and to invite the audience to think about the events and phenomena that occur in society.
