I don't know anything about European film censorship, but I did study the American Production Code, whose first chink in its armor was Otto Preminger's The Moon Is Blue. What most filmgoers might not know is that Preminger filmed two versions at the same time using the same sets; the German version was entitled Die Jungfrau auf dem Dach (literally "The Virgin on the Roof"). In America, it was a huge barrier-buster to discuss virginity in a movie (or even say the word), and for a girl to contemplate going to bed with a man she just met mere hours ago - in what was supposedly a light comedy.
The biggest difference between the two versions is the age of the main love interest. In the American version, William Holden is significantly older than Maggie McNamara. In the German version, Hardy Kruger is only six years older than the young Johanna Matz. When the "other man" shows up and conducts his own "counter seduction" plan with the girl, in the German film, he's immediately a father figure to her. In the American one, since Bill is also older, when David Niven arrives, it's not as clear-cut as to who she'll pick. It's more of a love triangle rather than a regular romance with a helpful older fellow providing some perspective and gentle nudges.
I'm just not a fan of this story and screenplay. I can't stand Johanna Matz's character. She's supposed to be twenty years old, but she has the maturity of a child half her age. Her personality is so off-putting, it's hard to believe the ridiculously cute (and experienced) Hardy wants anything to do with her. She's annoying, immature, strange, nosy, inappropriate, controlling, self-centered, and unrealistic. Plus, she won't stop talking! This is a very wordy flick, so you've got to read those subtitles fast. It's not my cup of tea, but then again, I've never been one to find "kooky" charming. The best part of the film was seeing the adorable cameo in the end of William Holden and Maggie McNamara (and in The Moon Is Blue, Hardy and Johanna give the cameo).
