It's on the tip of my tongue.
It includes tribal types dancing, a really long shot of an old man monkey sitting thinking in a hot spring, fluffy yellow chicks on a conveyer belt, people going up and down escalators ... and loads more.
It's sort of a cinematic journey from the natural to the mechanised world.
It's similar to Koyaanisqatsi / Powaqqatsi in that there are no actors or dialogue and there are lots of stunning long shots.
It's driving me mad. I want to do my christmas shopping now and order it from Amazon but I can't remember.
