Many movie musicals fail because they can't escape a stagebound feeling. The Sound of Music mostly escapes this by shooting on location all across Salzburg, but even the indoor sets feel massive. The von Trapp mansion feels appropriately enormous, never moreso than in my best shot:
The shot, coming immediately after the Captain has realized how much Maria has impacted his children, has incredible depth; fitting considering how much emotion is pressed into a single frame. It's simply an incredible shot.
This is what I think about when I think about love.
For my money, one of the funniest shots from any movie.
