Zimmer told in an interview that he decided to score this film because he received an OScar fo The Lion King and he knew that expectations would be high. He wanted to do a terrible score so in the next time he can compose anything he want. I know it sounds stupid for the first, but hey there is some logic inside.

I'm trying to fins this on the web if I find it I'll post it.

P.S. I think the heroic theme is beautifull. Which can also be herd in the LETTING GO song.
