Documentary filmmaking requires research to provide the context, footage and other visuals, narration, and interviews that will appear in the film. There are several types of research that documentary filmmakers might undertake, including archival research, academic research, and in-person interviews. Documentary filmmakers often choose subject matter they are passionate about, and a great documentary can be about any non-fiction, real-world subject. Indeed, sometimes the truth is stranger than fiction—and often more interesting. Many filmmakers are realizing this, choosing to delve into nonfiction narratives and bringing them to both the big and small screen. In fact, we are in the midst of a renaissance in documentary storytelling that has been going strong for more than three decades.
