21. The Doors, 'The End' in 'Apocalypse Now' (1989)
Vietnam movies seem to get all the cool songs, but it's only because Francis Ford Coppolla showed them how. Apocalypse Now wasn’t the first great film to use "The End" – that would be Scorcese’s 1968 Who’s That Knocking On My Door? But as "The End" crawls through Martin Sheen’s war-ravaged brain, Apocalypse Now taps into the late Jim Morrison's heart of darkness. It brought the posthumous Morrison cult to a whole new level; a couple of years later, Jim appeared on the cover of the Rolling Stone with the best headline ever: "He's hot, he's sexy and he's dead."
