This Is Spın̈al Tap is a 1984 mockumentary directed by Rob Reiner and starring members of the semi-fictional heavy-metal/hard rock band Spinal Tap. The film is a mock rockumentary that satirizes the wild personal behavior and musical pretensions of hard-rock and heavy-metal bands.
The three core members of Spinal Tap, David St. Hubbins, Derek Smalls and Nigel Tufnel, are portrayed by the American actors Michael McKean and Harry Shearer and British American Christopher Guest respectively. The three actors actually play their musical instruments and speak credible British English throughout the film. Reiner appears as Marty DiBergi, the maker of the documentary. Other actors in the film are Tony Hendra as the group manager Ian Faith and June Chadwick as St. Hubbin's interfering girlfriend Jeanine. Actors Paul Shaffer, Fred Willard, Fran Drescher, Bruno Kirby, Howard Hesseman, Ed Begley Jr., Patrick Macnee, Anjelica Huston, Dana Carvey and Billy Crystal all play supporting roles or make cameo appearances in the film. Scream queen starlet Brinke Stevens appears in an uncredited cameo as a groupie or girlfriend of a band member.
