Halloween is a horror movie classic. Its iconic synthesizer score is among the most recognizable movie themes of all time. The unmistakable "doo-doo-doo" is right up there with the legendary themes from Star Wars and Jaws to Superman: The Movie and Batman. It took director and co-writer John Carpenter, who also composed the music himself, less than the running time of the actual movie to come up with the movie's legendary theme. In a new interview with Consequence of Sound, Carpenter revealed he conjured the theme in just an hour and the entire score in only three days.
