A documentary film
is an audiovisual production, which “supposedly” presents the reality as it is.
“Supposedly” here refers to the ambition of eliminating any filter and/or bias, with which the author(s) may influence this transmission of information.
A mockumentary film
, which American director Michael Moore made popular at the end of the ’90 with his academy award winner “Bowling for Columbine,” presents the author’s perspective, point of view, and even opinion, as a legitimate part of this “reality.”
Is a mockumentary more “honest” than a documentary?Not necessarily.
An author may try to stick to an ethics of impartial storytelling and present enough sources and voices in order to limit inevitable distortions.
On the other side, the author of a mockumentary, may disregard any intellectual honesty by claiming that the video production was not intended to present reality any way.
