When filming the sound of music in the scene where Liezel is dancing in the gazebo during the song 'I Am Sixteen Going On Seventeen', where she dances from bench to bench, she actually went through one of the panes of glass on the first jump and sprained her ankle because there were two pairs of shoes she had for that scene (one with rubber grips and one without). The ones with rubber grip were meant for the actual filming NOT the rehearsal but she had been rehearsing with the ones without rubber grip and someone forgot to change them. She was OK but she had to do the dance with a bandage on her ankle.


When Julie Andrews is singing "I Have Confidence" she trips. The trip was completely accidental, and not choreographed, but the director felt it was in character, so he left it in.


When Julie Andrews is singing "I'm confident" she goes through a little tunnel. There is a cameo appearance of the real Maria von Trapp, who you can see to Julie Andrews' left.


Many years ago, Maria von Trapp was asked if the movie was pretty close to real life, and she replied, "Yes, except for one thing." She amusingly explained that when the family was crossing through the mountains, they were definitely NOT singing, unlike the film.


In the end when the family is climbing over the hills to safety, it is not really Gretl on the shoulders of Captain Von Trapp. On the DVD, it's revealed that while in Austria, Kym Karath gained a lot of weight. This was one of the last shots filmed and so she was a bit too heavy to be carried on Christopher Plummer's back, so he requested a lighter double.


When the Captain and Maria were singing in the gazebo, they had to just show their shadows because they would laugh too much in the light, so they hid their faces.

Wierd people these people are.
