I never saw the Sorcerer. I heard it's supposed to be a cinematic masterpiece.
The movie Legend is NOT a masterpiece, although I actually still like it, but if you ever watched (heard) the European cut which has a symphony orchestra soundtrack, you would realize how amazingly fitting the Tangerine Dream sound track is for it. Nothing against the orchestra soundtrack, but Tangerine Dream did an amazing job creating a fantasy ambiance for this movie;

You brought it up before I could. SORCERER is one of my favorite underrated films.
Horrible title, though. Probably should have called NITRO, or something like that.
