10. An American Tail
Yes, it seems odd to put the score for a children's film on this list, but Horner's score for Don Bluth's story of a Russian-Jewish immigrant mouse references everything from Stars and Stripes Forever to Gilbert & Sullivan. Obviously, the centerpiece of the film, "Somewhere Out There," goes a long way toward solidifying the film's place on this list. It's the rare ballad that succeeds not in spite of but because of its over-the-top emotion.
Using jungle percussion and Old West flourishes to make the world of Avatar seem at once exotic and familiar, James Horner grounded a CGI-heavy movie starring blue aliens with a startlingly human score.
8. Field of Dreams
While Horner's sci-fi scores are surprisingly earthy, his music for a movie about baseball set in a cornfield (how American is that?) has moments that are unexpectedly space-y and ambient. Of course, gently triumphant strings and horns keep things from getting too out-there -- but there's just enough to establish the film's supernatural element.
7. A Beautiful Mind
Although it contains elements of his 1999 score to Bicentennial Man (which some critics held against it), this is the superior score. The haunting, careening "A Kaleidoscope of Mathematics" is one of his finest moments
6. Apollo 13
Horner's score hits all the right notes in Ron Howard's historical dramatization, emphasizing the vast loneliness of space, the creeping danger of the Apollo 13 mission and the warmth of familial love.
The rare Horner sci-fi score that doesn't comfort the listener, his work in Aliens proved he can create music to evoke dread, suspicion and greed as well as more heart-warming, sentimental fare.
4. Star Trek II: The Wrath of Khan
His first true triumph, the soundtrack to the second (and still greatest) Star Trek film features some of his very best work. He captures the against-all-odds optimism of Captain Kirk, the single-minded, brutal bloodlust of Khan and the quite, selfless dignity of Spock's death. Best of all is his music for the climatic final battle, which gives John Williams' Star Wars score a run for its money.
From the woodwind instrument that provides the romantic, resolute main theme to the haunting "Freedom" suite to music of rural, medieval Scotland, Braveheart finds Horner deftly scoring scenes intimate, universal and inspirational.
Haunting, somber and majestic, the score to this Civil War drama was created in association with the Boys Choir of Harlem. When they sing the wordless main title, you could almost believe you're hearing the voices of ghosts from the past who need to tell their story.
Certainly his best-selling soundtrack (it's one of the best-selling albums of all time), Titanic is also his most decorated: It nabbed him two Academy Awards (best original dramatic score; best original song for the smash hit "My Heart Will Go On"). Horner captures the haughty arrogance of the aristocracy, the blue-collar joy of the working class and the inevitable death that awaits most on the ship. And, of course, there's the immortal "My Heart Will Go On," the powerful ballad that provides the film with its emotional denouement.
