As the whole movie is parodying the whole 50th science fiction the soundtrack is also a kind of parody of the retro-futurism of the early space era. Taking huge influence fro Bernard Herrmans The Day the Earth Stood Still Danny Elfman created a beautiful work switching dynamics between retro-space ambient parts and classically influenced orchestral pieces. Not forgetting the extensive use of Theremin, one of the earliest electronic instruments widely used in soundracks of the space era movies.
Kicking of with marching main titles the movie crashes into a big story of alien invasion and human resistance. While the humans are portrayed with more classical tunes with influences from classical and modern composers, the most interesting part are the Martians. Their parts include the Theremin, synths, minimal string arrangements, a bit tribal percussion and ambient stuff. The masterpiece is the Martian Lounge, great relaxing lounge, Spanish influences and a truly retro-space vibe moving into a dramatic middle part.
One of my favorite soundtracks.
