The Star Wars theme had different orchestrations for Episodes IV-VI and I'm just wondering why John Williams didn't do it with the prequels?
The star wars theme is essentially Luke's, leias ,kenobis[force theme]and vaders theme all rolled into one. It's probably because Luke and Leia aren't around in the prequels so the leimotifs needed to change accordingly.
No. He/she's talking about the opening crawl music, which was only recorded once for TPM and used in all three prequel films. I'm assuming it was done to save time/money.
Why shouldn't it be? Different recordings set up different moods, however minute, for each of the OT films. It's always left a bad taste in my mouth that it wasn't recorded for AOTC and ROTS.
