An interactive documentary utilizes multimedia tools like photography, text, audio, video, animation and infographics to create a nonlinear production, different from traditional linear documentaries. Interactive documentaries often feature interviews where the filmmaker can include or remove questions, and the responses from interviewees can provide their perspective or opinion on the story. They commonly take an investigative form where the audience is directly engaged, with informal interviews in long takes and location shooting with handheld cameras alongside voiceovers.
