Primary is a 1960 Direct Cinema documentary film about the 1960 Wisconsin Primary election between John F. Kennedy and Hubert Humphrey for the United States Democratic Party nomination for President of the United States.
Produced by Robert Drew, shot by Richard Leacock and Albert Maysles, and edited by D. A. Pennebaker, the film was a breakthrough in documentary film style. Most importantly, through the use of mobile cameras and lighter sound equipment, the filmmakers were able to follow the candidates as they wound their way through cheering crowds, cram with them into crowded hotel rooms, and to hover around their faces as they awaited polling results. This resulted in a greater intimacy than was possible with the older, more classical techniques of documentary filmmaking; and it established what has since become the standard style of video reporting.
In 1990, this film was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
