Bill Nichols asserts that a central function of documentaries is the act of representation. Broadly defined, representation means to stand in for someone else (whether it is an individual, a group, or even an institution) and to show them in a particular light. Although documentaries often seem to present unfettered access to someone else, the other's voice is always framed through the choices made by the filmmaker. In your opinion, who does Oppenheimer represent in his film The Act of Killing (2012)? Is it an individual, a group, or an institution? In what light or perspective does he shown them?
