Continuity mistake: In the movie, notice how the red sport utility vehicle driven by Bill Paxton goes from shiny and clean to very dirty and dusty, from one shot to the next, all within the same scene.
Revealing mistake: In the climax scene, Joe is climbing up the Ferris Wheel. He is huge, and weighs a ton, but his strong hands do not break a single lightbulb on the framework of the wheel.
Continuity mistake: When Joe helps the leopard to escape the sun on the floor changes between shots.
Answer: The song was written for the movie and is called "Windsong". The lyrics were originally written in English by Will Jennings then translated into whatever language that is. The music is written by James Horner (Titanic). The original lyrics were: "Sing a song and for a moment you will be visited by the wind. Sing a song and for a moment dream sweetly of the wind. Sleep now until the night is dawn. The wind and the night song, they are there. However the song, my child, will go on forever."
