Dziga Vertov was a Soviet pioneer documentary film and newsreel director, as well as a cinema theorist. His filming practices and theories influenced the cinéma vérité style of documentary movie-making and the Dziga Vertov Group, a radical film-making cooperative which was active from 1968 to 1972. He was a member of the Kinoks collective, with Elizaveta Svilova and Mikhail Kaufman.

A documentary film or documentary is a non-fictional motion picture intended to "document reality, primarily for instruction, education or maintaining a historical record". Bill Nichols has characterized the documentary in terms of "a filmmaking practice, a cinematic tradition, and mode of audience reception [that remains] a practice without clear boundaries".
