Hi, I am reading the book Wonder with my kids in class.

Towards the end of the book, the main characters are watching the musical The sound of Music.

Only a few of my students had ever heard of the movie. I thought it might be cool to have them watch it, but I have only 135 minutes (max) at my disposal. The original movie is almost 3 hours long. Does anyone here know of a shortened version I could show in class (three 45 minute lessons)?
