John Williams composed the Jurassic Park theme for Steven Spielberg's 1993 film Jurassic Park, where its gentle, majestic melody became closely tied to the first sight of living dinosaurs on screen. The theme has since become one of the most recognisable pieces of film music, instantly signalling wonder, scale and adventure even without any picture. Online, creators reuse short clips of it to frame reveals, entrances and parodies, because listeners recognise it within seconds and understand the joke before anything is shown.
