Ok, my suggestion is not for the usual action movies fan...
http://en.wikipedia.org/wiki/Qatsi_trilogy
the entire Qatsi's collection, AND Baraka... a serie of documentaries -- without a single word said -- ... for the music, for the quality of the images, for the content itself... a real study of the human nature. you want to know how people ARE everywhere on the globe, this is the stuff to look at.
