Composed by John Williams, the Imperial March first appeared in Star Wars: Episode V – The Empire Strikes Back in 1980 as the theme for Darth Vader and the Galactic Empire. Its militaristic brass became one of the most quoted film themes of all time, performed in concerts, parodies and trailers for decades. Online, creators reuse the Imperial March alongside other Star Wars clips like the Utini cry for instant sci-fi villain jokes, and its opening bars alone are enough to signal who is in charge.
