This Is Spinal Tap (1984)
This Is Spinal Tap is an American 1984 rock music mockumentary written, scored by, and starring Rob Reiner, Christopher Guest, Michael McKean and Harry Shearer. The film portrays the fictional British heavy metal band Spinal Tap. Directed by Reiner, the movie satirizes the wild personal behavior and musical pretensions of hard rock and heavy metal bands, as well as the hagiographic tendencies of rock documentaries of the time. Reiner and the three main actors are credited as the writers of the movie because much of the dialogue was ad libbed by them. Several dozen hours of footage were filmed before Reiner edited it to the released movie. A 4½ hour bootleg version of the movie exists and has been traded among fans and collectors for years. The three main members of Spinal Tap—David St. Hubbins, Derek Smalls and Nigel Tufnel—are played by actors McKean, Shearer, and Guest, respectively. The three actors play their musical instruments and speak with mock English accents throughout the movie. Reiner appears as Marty Di Bergi, the maker of the documentary. Other actors in the movie are Tony Hendra as group manager Ian Faith, and June Chadwick as St.
