Unforgiven, the Clint Eastwood film, has very clear & concise surround effects and some very cool thunderstorm sounds. The Extended Directors Cuts of the entire LotR trilogy is phenomenal sounding, too. The Red Violin sports a superb sounding soundtrack, much of it played by Joshua Bell. Jason X is a fun slasher/comedy with some eyesocket-rattling bass. Master & Commander: On the Far Side of the World is a fine film with a great soundtrack, and The 13th Warrior also has a fantastic soundstage with great effects.
