You are correct, Mark Walton! Hence, the scene where the nuns screw up the Nazi cars and say that they're sorry, but they have sinned! LOL!
Here are a few differences (some may have been mentioned, some not! and I know that I will come up with more as I go, so I apologize...) :
In the movie, Elsa tells Maria the Captain's in love with her...in the staged version, Brigitta does.
The movie Laendler sucks...dancing real Leandler moves is much more beautiful to watch and it's A LOT more difficult!
Lonely Goatherd...IMHO I believe it's better in the bedroom scene than the "puppet show" that's in there for no reason really...I've done it both ways...(I prefer Lonely Goatherd in the bedroom scene because it makes more sense and, if staged correctly, can really be a bright spot in the show that shows the growth of the relationship between Maria and the children.)
I've also done "Favorite Things" in the bedroom and a throw-away Goatherd scene and "Favorite Things" in the Abbey with Mother Abbess with Goatherd in the bedroom scene. I prefer the latter. (See discussion above)
Obviously, the key to SOM is different in the movie version than the stage version. I have sung both versions...I really like the higher key because it's very carefree, but I also love the lower key because it has a very honest tone to it.
I agree with everyone on the fact that cutting "No Way to Stop It" and "No Way to Stop It" is a travesty! The political climate at the time is what drives them to leave their home!
"Something Good" vs. "Ordinary Couple"...I like "Something Good" better because it's simpler and more honest. (A reprise of "Ordinary Couple" is usually played during the wedding scene, for those who like it, but don't LOVE it!)
