''We live in fictitious times. We live in a time where we have fictitious election results that elect a fictitious President. We live in a time where we have a man sending us to war for fictitious reasons… Shame on you, Mr Bush, shame on you.’' -  Michael Moore

Mockumentary (also known as mock documentary) is a genre of film and television in which fictitious events are presented in documentary format. These productions are often used to analyze or comment on current events and issues by using a fictitious setting, or to parody the documentary form itself.[1] They may be either comedic or dramatic in form, although comedic mockumentaries are more common. A dramatic mockumentary should not be confused with docudrama, a genre in which documentary and dramatic techniques are combined to depict real events.

Mockumentaries share much with the documentary genre:

They use the same codes and conventions as documentary, such as an authoritative narrator, 'real’ footage of events, archival photographs, interviews with apparent 'experts’ and 'eyewitnesses’, and so on.

Mock-documentaries 'work’ because of the assumptions and expectations that we have of documentary. When we see a text that looks and sounds real, we tend to naturally believe it.
