Beautiful Preisner score
Zbigniew Preisner's music gives this movie its soul especially the haunting main theme with background thunders imitating the magnificent waterfalls of the Amazon Beginnings. It's as beautiful as Ennio Morricone's "The Mission" score.

If you listen to the tidbits of tracks 1,5,7,9 and 14 you'll get an idea what I'm talking about. I'm pretty sure Gabriel Jared was inspired by this score when he composed his theme for "The English Patient".
