1984 · Rob Reiner
How This Is Spinal Tap has been received, argued over, and remembered.
Modest box office in 1984 — and famously, some early audiences didn't get the joke, wondering why anyone would make a film about a band this bad — but it grew into the definitive mockumentary and was added to the National Film Registry in 2002.
The perennial fan debate is whether any mockumentary since — including Christopher Guest's own films — has ever topped it, and whether musicians love it or find it too painfully accurate to laugh at.
'These go to eleven' became so ubiquitous that 'up to eleven' entered the dictionary, and IMDb famously rates the film on a scale out of 11. Real bands from Metallica to U2 have described watching it on tour and wincing in recognition.
The undisputed template of the mockumentary — a 'you must have seen this' comedy touchstone that every band-doc parody since gets measured against.
Influences Rob Reiner has publicly named — the director's own word, distinct from the inferred lines of influence.
