The one thing that really fascinates me in films is it's soundscape. The intercourse between sound and moving image is like marinating good foreplay and intensive sex. Really the pleasure of watching a film doubles manifold when you also experience a great sound scape.. it is like the moods intensify! Which is why I guess there was such liberal usage of punching sound effects Dishum Dishum in hindi films and obviously the heroine would be crying hoarse to lend emotional drama. But if anyone's seen The Truth about Charlie, you'd come across this amazing use of Aznavour's tracks like honeyed texture all across the power packed intense drama sequences. Wang Kar Wai also used soulful operatic sounds in his flick In the Mood for Love. It conjured up this desire to be really be "in the mood for love". Ever wondered why a cinematic experience in a theater is so intense, so passionate.. surround sound my dear, surround sound! It sucks you into the plot even involuntarily and it makes your pulse a little faster. If I watch the same film at home without the fancy gadgetry of sound I would be tempted to take breaks, do something else etc etc...
2046 had a halluconegic background score that was apt for it's set up and storyline! A man who takes a fast train into the year 2046 to rejoice lost memories of love. Incidentally the author who writes 2046 in the film is writing the book in the hotel room with the number 2046...
While Tarantino roped in Nancy Sinatra for Kill Bill track who would have ever wondered the protege and daughter of a cult figure would so masterfully croon on a racy pop flick and lend authenticity...
So as many would wonder why an experience in theater is far richer than a simple viewing at home.. pay attention to what the sounds are telling you! It reveals a whole new side of the plot... you thought never existed!
