:thmbsp:Taxi Driver is hands down my favorite movie/score
Dimitri Tiomkin's Guns of Navarone. (Ever notice that his scores always sound the same, as if they were recorded in the same studio by the same engineer.)
I'd agree with a lot of the titles mentioned. Several people mentioned "The Last of the Mohicans." That's the only film I can remember watching where DURING the movie I was thinking, "This music is great! I have to go get the soundtrack to this!"
