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".
