Expository 

     Expository documentaries are films which expose a person or a topic, and emphasize verbal commentary and argumentative logic. They speak directly to the viewer through narration, a narrator with an authoritative tone. This voice is also known as the “voice of god” in the realm of filmography and in literature. The “voice of god” is an omniscient voice which often seems objective. The film An Inconvenient Truth (AIT) is an example of an expository documentary. AIT is a controversial film by Al Gore which aims to highlight the dangers our society faces from climate change, and suggests immediate actions that need to be taken. Al Gore himself plays the narrator.

The main conventions used in expository documentaries which could help the viewer identify it are:

· Commentator (voice of god)

· Persuasive techniques


· The combining of facts and opinions

· Rhetorical Questions
