Hey,
Here is the German Version of “Up”. The German called UP “Oben”. This ist the Special Edition with One-Doublsize Disc. All the Special Stuff and short Movies. I love the Movie.
I want to see the German version once as well. I have to practice my German anyway… ‘Oben’ sounds cool. In Dutch it’s just called… well, ‘Up’. xD Original I know. 
I think Muntz is rather disappointing in the German version. The character somehow lacks believability, which Christopher Plummer manages to convey with ease.
However, I wholeheartedly recommend seeing Ratatouille in German. This is simply the best German dub of all time - it even beats the already pretty awesome English version.
I am currently studying German. I’ll have to look into this.
About the Ratatouille dub: It’s an American movie about France dubbed in German!
Ich spreche Deutsch! Deutsch is sehr spass… Ich Liebe Oben!
