THIS IS SPINAL TAP (1984)
ROB REINER
Plot
An inspired and brilliant mockumentary recounting the history of a crap British heavy metal group and following them on a disastrous tour of the US. This movie takes apart every cliche that ever graced a rock documentary and every vanity or folly to haunt overblown rock groups. So realistic that American audiences thought the band was real... Voted third funniest film by Observer readers in a 2007 poll.
