I've always maintained that 'star wars' borrows a lot from wwii British war movies.
The Imperial Music is a direct lift of the opening titles music of 'Ice Cold In Alex
More so the trench run directly lifts dialogue and imagery from dambusters.
If you've time have a look at these two, its worth it.
and the theme music 'lift'.... at 1.40 its near identical to the music in star wars
