When I first saw TPM, at the Australian premiere, I was disappointed how unlike "Star Wars" the film was. One of the main factors that influenced this was the musical score.
A lot of the music we associate with the OT is linked to specific charactes that do not appear in the prequels, ie the Imperial March for Vader and the Emperor, Luke's theme and Leia's theme etc. I know John Williams tried to incorporate some themes from the original trilogy score into the prequel scores, such as the Imperial March as an innocent children's theme for child Anakin and the Imperial March at the end of AOTC (Palpatine on the balcony), but I still think the Prequel Trilogy could benefit with more of the OT music.
I am interested in hearing from other OT lovers, what OT music do you think would have worked well in the prequel's? The best example I can come up with is in Magnolia Fan's edit of Ep1 with the "Trench Run" music from ANH being used in the final lap of the Pod Race scene. That was brilliant and definitely enhanced that scene tremendously!
