Fifty years after the original release of this beloved Oscar-winning movie version of the Rodgers and Hammerstein musical, Diane Sawyer presents this 20/20 special looking back at it all, with the film’s star, Julie Andrews, as co-tour guide. Their travels take them from the movie’s production notes, where we see storyboards for an unused hedge maze sequence suggested for the “Do Re Mi” number, to Austria, where the hills remain alive… along with the descendents of the Von Trapp family.
