Idealogy is the set of values and beliefs belonging to an individual group, social class or specific culture. Idealogy can be explicitly apparent in the filmmaking medium. For many years, art has been viewed as an element with a double purpose; to express ideas and teach as well as provide pleasure. Idealogy is the teaching and expressing of ideas in films.
Ideological explicitness can be divided in three broad categories: neutral, implicit and explicit. In films reflecting neutral views of ideology, the writing is more focused on the purely entertaining values. The film is focused on action and pleasure more than teaching or persuading. Big summer blockbusters are great examples of films with neutral ideologies. The films were not produced to raise questions or expressa certain set of beliefs, but to simply entertain for a few hours. These films are more accessible to the public, as the story is smooth and simple. The implicit category is more focused on opposing sets of values. Usually, the antagonists and the protagonists represent certain value systems the conflict with one another. The ideoligical view of the filmmakers may not be entirely clear, as the characters simply represent the values rather than selling the values to the audience. In the explicit category, the films intend to teach or persuade the viewers. The film also seeks to entertain, but the values presented are at the forefront. Political, biographical and documentary films are under this category. Films with sociological issues presented also fall under this category. THX 1138 is an example of an ideological explicit film.
THX 1138 is the name of the title character, played by Robert Duvall. In the film, an underground city is home to thousands of humans. Every day, they are intructed to take certain drugs to supress their emotions. The inhabitants are forced to worship a godlike being know as "OMM". They are also not obligated to choose their own "roommate". THX 1138 decides to experience what happens without the drug, and his life is immediately changed. The film asks many questions about the control of the powers above us. How much control is too much control? When does our government impede our rights as human beings? The views expressed in this film were a great example of an explicitly ideological film.
