Billy Wilder can't really produce bad comedies, can he? It may not be his greatest work but as a German (who is too young to have experienced this period or the Cold War in general) I found this (fictional) American view on post war Berlin particularly interesting. It's Germany alright, but it seems like a foreign country to me. Fun fact: there used to be a Coke factory in my town as well. It closed when I was very young. I can hardly remember it. But they had the same kind of Coca Cola sign on their roof like the building in this movie. No wonder: the location in the movie used to be a Coke factory for real.

It's also great to see German (speaking) actors like Pulver or Buchholz in their prime. How beautiful and promiscuous she was. Tiffin is also great. Plus, I enjoyed b/w imagery, 60's design and the glimpse into the society of that time (I have difficulties to tell what's fiction and what's reality though.)

The plot is kind of entertaining. Comedy elements are solid if you like the typical cartoon-ish style of comedies of that era. In hindsight it's kind of weird that they shot a lighthearted comedy against the backdrop of the 1961 events in Berlin.
