How about Adolf?
The best German film I've seen since "Das Boot" and "Downfall".
This is proof you can have great Non-WWII German films, AND that German comedies do exist!!
The entire movie takes place over a family dinner party, where an expectant father announces that he's naming his son Adolf. No Neo-Nazi material or anything really controversial. Just very witty and hilarious banter. I watched with subtitles, but it doesn't take away from the comedy.
There is even an awesome scene where one character goes on an endless, but structured and poignant rant. I don't know if that was one take, but it was a sight to watch!
