tbh I don't get why he never had the Austrian citizenship to begin with, born and living in Austria for such a long period of time he surely could have just given up his German passport for the Austrian one. But then he lived in Hamburg and Berlin (and London) for years too (although with the EU it doesn't really matter anymore). I guess the German citizenship was just easier for him to get jobs tbh, but he doesn't want to be associated with it as such. Until it came out after his 2009 Oscar win that he held a German passport and not an Austrian one, he wasn't actually labeled a German actor anyway in Germany.
