Keep thinking about "Green Leaves of Summer". I'm actually sitting through The Alamo to see how it was used the first time around.
At the movie theater for IB, this music, (written by Russian emigré Dmitri Tiomkin for The Alamo?), immediately told me Inglourious was a far cry from the kid-oriented special effects crap that all movie previews are about now. I felt myself breathing a huge sigh of relief and settling in without knowing any more than that.
1, it's a waltz, 3/4 time, very famous in Austria as in Blue Danube. Second, the accordian, very French, brings to mind the pre-rock world of intellectuals and spies. We are all past the "ism-schism"s of Europe's hey day, which is healthy, but being post-intellectual is not all that interesting.
I read up on the making of the Alamo. John Wayne went through a lot to present his own personal vision of this movie on the screen. So even though it's kind of boring and historically incorrect, it merits some respect.
Finally, being completely historically incorrect is also Inglourious Basterds territory. Maybe this song also tells you that's what coming, in QT's massive encyclopedia brain.
