I have seen this film and I loved it. It is an homage to the evergreen comedies from the 40s and 50s. The actors Anne Brendler and Heio von Stetten are charming and lovely and sexy. The music swings You through beautiful images of Berlin and the fast pace pushes You from one ironical, witty and romantic scene to the other. The humor in the dialogues is very nice. Any similarities to certain screwball comedies might be intended, I believe. The director has made a great job.
