Direct cinema, sometimes in the form of the observational cinema verite, is a way to make the audience feel as though they are observing events as they are actually happening. Instead of using music and interviews to try and give the gravity of a situation, the viewer is invited in to watch and feel as they would naturally. Of course this is a filtered perspective as all filmmaking is, but it is still meant to give the appearance of uninterrupted involvement. If your film is focused around direct cinema, which watches as events take place, then you may not want to interrupt that feel to have interviews that are framed and executed in classical film fashion. The majority of the footage is more “on the spot,” and therefore cutting away to studio interviews can break from the rhythm that you have established. In this situation you can make your interviews fit the aesthetics of direct cinema while still being as prepared as any.
