I'm a huge fan of Sir David Attenborough, so Blue Planet and Planet Earth are two that I definitely recommend, as well as his more recent Frozen Planet, which focuses on the North and South Poles.
Since you like Nazi hitory, you might enjoy "Triumph of the Will" (german: "Triumph des Willens"), a Nazi propaganda film from 1934 created by Leni Riefenstahl and comissioned by Hitler himself. It gets quite slow and boring at times, but it is a very important piece of history that you should not miss.
