By soundtrack, I mean both score and song. I’m excluding musicals for obvious reasons. John Williams is overrated crap. Enjoy. L’Atalante (1934) – The greatest score of French composer Maurice Jaubert. Covers only around five minutes of screen time, but perfect. Casablanca (1943) – Famous for it’s use of songs, like “As Time Goes By” and “La Marseillaise,” but the score is Max Steiner’s best. Vertigo (1957) – Bernard Herrmann’s masterpiece. Casino (1995) – Scorsese mixes period rock and blues with bits of scores from French new wave films and classical composers. A masterpiece of fusion. The Unbearable Lightness of Being (1987) – The entire score was culled from the works of Leos Janacek. You would swear Janacek scored the film himself if he hadn’t died 60 years earlier. Jules et Jim (1961) – Georges Delerue’s masterpiece. And the French hippy folk songs mixed in actually work. Happy Together (1997) – Maybe the oddest score ever; a Hong Kong film that mixes Piazolla tangos with Zappa guitar rifts and, of course, The Turtles. A Streetcar Named Desire (1951) – It was the first movie to use a jazz score, and it’s still the best. 3:10 to Yuma (1957) – One the Western’s most underrated entries also contains its best score.
