The movie is one of the numerous German propagandist movies of that era. Featuring lots of high-class stars, but the plot is rather dull. Shipmen having a short holiday, falling in love with some dames, then called back to their ship for fighting in the Atlantic.
But: It is very obvious that this movie was the template for Wolfgang Petersen, making his world-famous "Das Boot" in 1981. The protagonists, even their physical appearance, several plot-lines, but especially the photographing of the movie seem to be at many points a black&white version of "Das Boot"! So this movie can be considered as a kind of "missing link" concerning "Das Boot", which makes it interesting for me.
