Documentaries document real events or situations using actual footage or reconstructions, with or without narration. The term was coined in 1926 by filmmaker John Grierson to describe a film about life on a South Sea Island. While documentaries present facts, their ultimate goal is to use those facts to make socially critical arguments and invite audiences to draw their own conclusions.
