The Hills Are Alive! Behind The Scenes With The Sound of Music

In The Sound of Music, Maria becomes the governess for the seven von Trapp children, which omits three of the children in the family. There may have been any number of reasons to focus on seven instead of ten. Not only would it have added more kids to the mix, but it may have also been seen as a further complication to the story line.
