You sort of expect the usual suspects to show up this far out on the list, so it's really surprising to me that Ben-Hur had such a big jump to an elite group. Kinda makes me want to watch the movie again, it's been a while.
Once Upon a Time in the West, though?
If that theme doesn't give you goosebumps, you better check your pulse or I better call the Ghostbusters, 'cuz you ain't here with the living, homeboy!
