Watch FMovies. Primary is a documentary film about the primary elections between John F. Kennedy and Hubert Humphrey in 1960. Primary is the first documentary to use light equipment in order to follow their subjects in a more intimate filmmaking style. This unconventional way of filming created a new look for documentary films where the camera’s lens was right in the middle of what ever drama was occurring. Preserved by the Academy Film Archive in partnership with The Film Foundation in 1998.
