This is a very interesting meme. It seems to mock not only the tendency of individuals on the internet to overreact but also the cartoon nature we a sign to Hitler. It also points out that the seeming lack of dramatic scenes of Hitler which we have been presented in the cinema. Of course the movie appears to be German, so perhaps my ignorance stems from my lack of familiarity foreign film. I would also assume however that perhaps this meme rose partly because of the lacks of other clips. A case of art thriving in it's limitation. We can't forget though that these clips are most defiantly, but at the same time we can see the potential for creative commons works to be "advertised" though internet memes. I am certainly much more likely to see this random German movie now that it is a more prevalent part of the culture.

Cowwithastickupyourass, although eloquent enough you display a total ignorance of culture originating from outside the US (which I assume you are from).

It is not a random 'foreign' film. It is a critically acclaimed Oscar nominated film (http://www.imdb.com/title/tt0363163/).
It is also one of the best films I have ever seen (and I am not German, only not so frigging narrow-minded as not to ever consume films produced outside of Hollywood (which, by the way 9 times out of 10 produces predictable crap aimed only at not scaring people away from the box office, rendering them devoid of any artistic or entertainment value)).

So, get out of your US comfort zone and see what the majority of the world's population (those outside of the US) are up to.
