Documentary film-making started off for informational purposes but graduated over the years through to reflect the persuasive creative ambition of the film-makers. Along with the aesthetic hues of romanticism and surrealism, the films have become more diaristic, self-reflective and experimental. The infant "actuality" art form of the yesteryears soon became the energetic activist threatening to topple the hegemonic powers of oppression. The film genre has extended much beyond the etymological sense of the term and had been visualized as doing so in a more than seventy-year old futuristic article by one of its founding auteurs and theoreticians, John Grierson as "Documentary is a clumsy description, but let it stand".
