Following on from a similar one I wrote for Japanese films on another site here, my list of 10 must-watch German films is also up:

What do you think of my choices? Let me know. And if you haven’t seen some of these, give them a watch!

I am only missing The Cabinet of Dr Caligari & The Testament of Dr Mabuse, the latter a Criterion Collection film. Both have now been added to my “buy list”.
Of the 8 films that I have already watched there are only 2 I wasn’t keen on, The Enigma of Kaspar Hauser & Wings of Desire.
Bar Run Lola Run (good), the remaining 6 films are very good/excellent.
