Documentary films are a genre of filmmaking that aims to document reality for the purposes of instruction, education, or maintaining a historical record. Unlike fictional films, documentaries present factual information and often explore real-life events, people, and issues, providing audiences with insights into various subjects. These films can take many forms, including biographical documentaries, nature films, and social issue explorations. They often utilize interviews, archival footage, and observational techniques to engage viewers and provoke thought, making them a powerful medium for storytelling and raising awareness about important topics.
