Film is used for education and propaganda. When the purpose is primarily educational, a film is called an "educational film". Examples are recordings of lectures and experiments, or more marginally, a film based on a classic novel.
Film may be propaganda, in whole or in part, such as the films made by Leni Riefenstahl in Nazi Germany, US war film trailers during World War II, or artistic films made under Stalin by Eisenstein. They may also be works of political protest, as in the films of Wajda, or more subtly, the films of Andrei Tarkovsky.
The same film may be considered educational by some, and propaganda by others, such as some of the films of Michael Moore.
