The movie starts showing the moon rising over a city showing car lights as long lines. A male chorus fairs something like "Kamma zu katzi" over and over again.
As I remember it there is a lot of impressive scenes in the movie.
Maybe the instructor is japanese.
Can anybody help with a movie title?

One of these possibly: Qatsi trilogy (http://en.wikipedia.org/wiki/Qatsi_trilogy)

Wow, spot on. KoyaanisqatsI was the movie I was thinking about, even though my recollection was wrong - the moon rising was in the middle of the movie and not in the beginning. Thanks Quinn F :-)
