Howard Shore's score saw off challenges from John Williams' Star Wars theme and Hans Zimmer's work on Gladiator to take top spot in the favourites poll for the fifth year running.
Williams had four pieces in the top 10 of the poll, which was organised by Classic FM, including work on Schindler's List and Jurassic Park.
Classic FM presenter John Suchet said: "The growing interest in film music confirms that modern classical music is as popular with UK audiences as ever.
"And I'm delighted to see that my personal favourite - Gone with the Wind - has made the top 20."
The station counted down the chart - listed in full at classicfm.com - in a programme yesterday.
