This Is Spinal Tap is a 1984 "mockumentary" directed by Rob Reiner and starring members of the heavy-metal band Spinal Tap. The film satirizes the wild behavior and musical pretensions of Led Zeppelin, AC/DC, The Rolling Stones, The Who, Queen, Aerosmith, KISS, Black Sabbath, Judas Priest, The Beatles, etc.
Much of the film was ad libbed, and several dozen hours of footage were shot before Reiner edited it down to the released film. A 4½ hour bootleg version of the film exists and has been traded among fans and collectors for years.
