What is a documentary?

A documentary is a nonfiction film that captures real events, people, or issues through a creative lens. While rooted in truth, different documentaries are far from dry recordings. They blend storytelling, voice-over narration, and cinematic techniques to craft compelling narratives that inform, inspire, or provoke debate. A documentary film typically includes interviews, archival and observational footage, voice over narration, or other filmmaking techniques that provide audiences with unique insights. Some documentary genres incorporate reenactments, animation, text overlays, music, and visual effects to enhance storytelling.
The different types of documentaries
- Observational
- Poetic
- Expository
- Participatory
- Performative

1. Observational types of documentaries
Observational types of documentaries adopt a fly-on-the-wall approach. Filmmakers observe and capture real-life events without interfering or directing the subjects. The aim is to present the subject matter with authenticity. Examples are:
- High School (1968): Documents the lives of Philadelphia high school teachers and students.
- Hoop Dreams (1994): Explores the dreams and struggles of high school basketball players in Chicago.
2. Poetic types of documentaries
A poetic documentary film uses imagery, metaphors, and symbolism to explore themes lyrically and subjectively. It’s one of the types of documentary that prioritizes visual storytelling over verbal exposition. Examples are:
– Sans Soleil (1983): A meditation on memory and cultural differences.
– Baraka (1992): A stunning exploration of human culture and spirituality.
3. Expository types of documentaries
An expository documentary film informs and educates audiences about specific topics by presenting facts, arguments, or explanations. They rely on voice over narration, interviews, statistics, and archival footage. Examples are:
– An Inconvenient Truth (2006): Al Gore’s presentation about climate change.
– Blackfish (2013): The controversial treatment of SeaWorld’s killer whales.
4. Participatory types of documentaries
In these productions, the filmmaker directly interacts with the subject, becoming part of the story through immersive portrayals. It’s one of the types of documentary that blurs the lines between observer and participant. Examples are:
– Super Size Me (2004): A filmmaker eats McDonald’s for 30 days.
– The Act of Killing (2012): The Indonesian death squad leaders.
5. Performative types of documentaries
A performative documentary film incorporates the filmmaker’s personal perspective, experiences, or narrative journey as a central character. It’s one of the types of documentaries that explores how a filmmaker’s presence shapes the audience’s understanding of the subject. Examples are:
– Fahrenheit 9/11 (2004): The Bush Administration’s response to 9/11.
– Tarnation (2003): Explores a director’s troubled home and family life.
6. Reflective types of documentaries
These examine the filmmaker’s thoughts, feelings, and insights about subjects or experiences. They involve self-reflection and a critical examination of personal perspectives. Examples are

– 13th (2016): Examines systemic racism and mass incarceration in the U.S
