This is a German propaganda film made in 1941, and it shows. It's in German and there are no subtitles, but from what I can gather there is no mention of Naziizm in the movie. I could be wrong, of course. If I'm right then that's pretty impressive for a movie made to glorify the Ubootwaffe.
One thing worth mentioning: Karl Doenitz plays himself.
[edit] Sorry about the link. I had it copied and everything, just forgot to paste it.
