Nightowl They probably thought that Austrian/German audiences would prefer the original German language film and it seems they were correct in this assumption.
Oh my dear - this is so true.
German speaking folks just don't expect people to speak English in a movie that is obviously placed in their home region. It feels just wrong. In the beginning I always thought the Captain belonged to the Royal Navy. Furthermore I wondered, why a british officer lives in Austria near Salzburg. (I immediately recognized Salzburg from the opening scenes; it is such a beautiful town.)
Then there was the landler dance. It is some dance, but not a landler. It is not even landler music at all. The composers found out, a landler is a ¾ beat and made something with a ¾ beat. But it sounds more like a waltz. Landler music is very different.
But the most strange scene was Edelweiss. I instantly thought, why can Lisl step in and know the melody and the text of this song? Then I thought: Okay - it is the oldest child, maybe she learned it up from her mother and remembers. This was my explanation and I was fine with it.
Then Edelweiss came again, but now the entire crowd was singing along. What? Why does everybody know this song? It is a nice song, but it does not sound like a song from the Alps. Especially in the refrain, the 2nd word "Edelweiss" is delayed like a syncopation. Something like this isn't used in the Alps region. Believe me, I grew up in a household with parents listening to a lot of traditional and regional music.
Something else? Yes - Do-Re-Mi. Nobody in Germany or Austria knows about Do-Re-Mi-Fa-Si-La-Ti-Do. We have our own letters for music - we think B is an H. But Bb is named B. This is what I learned as a small kid and I thought: Easy - almost the alphabet. I didn't think about why there is an H between A and C; nor if it makes any sense. I just accepted it.
About proper names for notes I learned as adult a few years ago when I started piano. It was a no-brainer to prefer the English names instead of the German ones. And by diggin into this topic a bit, I found out that Italy and France use Do-Re-Mi, but no letters. Maybe the Swiss could know it, because there use 4 languages: German, French, Italian, Romansh. But Austrians and Bavarians? No - they don't know Do-Re-Mi.
Anyway, how the Alps (Austrian/Bavarian) culture is displayed in SoM, it is very weird for us. They sing about schnitzel with noodles. Nobody eats noodles together with schnitzel. The usual side dish to schnitzel is something made of potatoes, like fries, potatoe-salad or fried potatoes. Sometimes spätzle, but never noodles. NEVER. (it is like ice-cream with ketchup)
Maybe imagine watching a movie made in Germany, but it is about Texas. And imagine a scene with a wedding in a church. And then imagine, after the priest has finished the ceremony and the couple kisses, all guests grab their revolvers and shoot in the air. Yelling Yee-Hah. Not to mention, everyone is wearing a cowboy hat. 🤠 What else 😂
