Such a pleasant film to watch. Norman is absolutely an amazing person and so talented clearly. It's amazing how the stars aligned for this production from top to bottom. Having so many interviews and stories from the actual people responsible for all aspects of the film made the difference for me. As well as the footage and images they were able to show which really helped tell the story and keep the audience interested and entertained. I went alone and was younger than everyone in the theater. I share this only to say what a great film for any age, and not even if you know or like the 1971 movie, but also an Interesting look at how films are made and how each department of a film works together and in this instance beautifully and successfully. Bravo...KUDOS TO THE DIRECTOR OF THE DOCUMENTARY TOO.
