This Is Spinal Tap

This Is Spinal Tap is a 1984 American rock music mockumentary comedy film 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 they ad libbed much of the dialogue. Several dozen hours of footage were filmed before Reiner edited it to the released movie.

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. Hubbins' interfering girlfriend Jeanine. Actors Paul Shaffer, Fred Willard, Fran Drescher, Bruno Kirby, Howard Hesseman, Ed Begley, Jr., Patrick Macnee, Anjelica Huston, Vicki Blue, Dana Carvey, Billy Crystal, Brinke Stevens, and Linnea Quigley all play supporting roles or make cameo appearances in the movie.
