The document discusses using either a participatory or expository mode for a documentary film. The participatory mode would involve the filmmaker taking part in constructing the documentary, similar to Sicko and Food Unwrapped, appealing to the target audience. The expository mode would use a narrator representing the target audience, relating to them and their interest, like March of the Penguins and Frozen Planet, providing a non-biased argument. The assignment discusses Chelsea Fashole, Luke Rosalin Zein, and Marisha Inoke, and Russ Monocillo's interest in these two modes.
