Trivia: Just in case some people don't know, most of the "German" in this movie is total gibberish. Some sentences are perfectly correct and properly spoken, as with the welcoming speech, the German soldiers and platform announces at the station, the "Ich liebe dich, mein Schatz", etc. But the learning tape, the conversations at the Culture Hall during dinner and the East Germany Anthem are just a bunch of "German-dutch sounding noises." Of course, it's even funnier to know that there are subtitles for all these with content that has nothing to do with it.
