This is Spinal Tap is widely regarded to be the first real mockumentary. It set the stage for Christopher Guest’s later directorial work, The Office and countless rip-offs, and Sacha Baron Cohen’s deep-cover comedy characters. The movie’s satire of the rock documentaries, pretentious musicians, and record label meddling was so pitch-perfect that U2’s The Edge said that when he first watched it, “I didn’t laugh, I wept.” But to most viewers, it’s one of the funniest movies ever made, with an infinite number of memorable quotes.
