This 1984 rock and roll comedy, directed by Rob Reiner, was a satire on rock documentaries, and told the story of an over-the-hill British heavy metal band. Name this film.

This 1984 film, presented as a "rockumentary," follows the fictional British heavy metal band Spinal Tap on a disastrous American tour. Directed by Rob Reiner, the movie satirizes the grandiosity and self-importance of rock bands and the documentaries that chronicle them. The band, comprised of members David St. Hubbins, Nigel Tufnel, and Derek Smalls, faces a series of comedic misfortunes, including malfunctioning stage props and a string of bizarre drummer deaths. The film is largely improvised, a decision that adds to its authentic and humorous feel.

Upon its initial release, "This Is Spinal Tap" had a modest box office performance, partly because many viewers believed Spinal Tap was a real, albeit unsuccessful, band. However, it quickly gained a cult following and is now widely regarded as a classic comedy and a pioneering film in the mockumentary genre. The movie's influence is significant, popularizing a style of improvised, documentary-style comedy that would later be seen in films directed by cast member Christopher Guest, such as "Best in Show" and "A Mighty Wind." The film also contributed the iconic phrase "up to eleven" to the pop culture lexicon, originating from a scene where Nigel proudly shows off his custom amplifier. The actors, all accomplished musicians, played their own instruments and even toured as the fictional band after the film's success.
