A mockumentary is a film or television program that takes the form of a documentary to parody or provide comic commentary on real events. The document discusses several examples of notable mockumentaries including A Mighty Wind, This Is Spinal Tap, and the author's own fictional mockumentary about a made-up creature. Mockumentaries use documentary techniques like narration, interviews, and depicting a subject's lifestyle or life cycle to give audiences a false sense of reality for comedic effect or to satirize certain views of culture, politics, or society.
