James Horner's score for Sneakers in 1992 heavily influenced his score for Legends of the Fall 2 years later in 94. Listen to the low piano parts in Legends and you'll recognize them from Sneakers.
Listen to 1:10 - 1:55 on track 7 of the Legends of the Fall score entitled "Farewll, Descent into Madness" and you'll hear these low piano parts clearly. Also check out 7:22 - 7:48 of the same track and compare it to the reveal in Sneakers when Cosmo opens the empty answering machine on the roof of the bogus toy company office building, and the camera drops down to waist level as that spotlight saturates his face. I've always been a huge fan of both scores but only recently realized how similar they are.
If this at all inspires you to check out James Horner's other fantastic scores, I'd direct you to Field of Dreams The Land Before Time and An American Tale.
