I saw this film in New York in June and loved it then and I just saw a press screener of the DVD - it is amazing what the filmmaker has done. In addition to being incredibly entertaining as a film, this is destined to be an invaluable historic reference. There are dozens of interviews with actors giving us a first person account of Broadway's Golden Age by those who were there, creating it.
The DVD has at leat 30 minutes of interviews with the cast of the upcoming (I hope soon) "Next Generation" including: Betty Buckley, Jason Alexander, Doug Sills, John Barrowman, Cady Huffman and Daisy Eagan. There are also deleted scenes, one has Marian Seldes on Katharine Cornell - I cannot imagine how this was not in the original film. The movie could have been twice as long and still held up. It's also fun to see the alternate ending on the DVD and the red carpet footage of the NY and LA openings. This is not a rental, you will want to own it and watch it when you want to be entertained, or inspired, or moved, or laugh. This film is incredible.
