Reddit reviews The Sounds of Star Wars

Haha, yeah I agree! In fact, Burtt and Lucas did go through each script and wrote actual lines for R2. Then Burtt crawled into a corner with his recorder and whimpered in the approriate tone for each line, then later combined it with a synth (something along those lines). I wouldn't be surprised if that was R2's actual line.

The sounds of Star Wars has about any sound effect you could need, and then I use Spotify for the music. I use a lot of Gustav Holst’s planets themes because they supposedly inspired John Williams.

So you are asking about how you should approach this? Sound design is incredibly complex and many film students aren't being taught as much as they should. Starwars is a good example because it employs leit motifs, great sound pans, and of course, a John WIlliams score. If it were me, I would do something about how the music enhances and colors audience perception of scenes and characters, maybe tie it into world building. If you're going for a more technique analysis approach there is a great book, http://www.amazon.com/The-Sounds-Star-Wars-Rinzler/dp/0811875466

I got this book for christmas a few years back, and it has tons of amazing info about Ben and the things they did to bring such good sound to Star Wars, for example: The giant underwater beast "There's always a bigger fish." in Phantom Menace, was actually Burtt's 3 month old daughter Emma, he recorded her growling and slowed it down to match the size and mass of the monster. and here is the clip
