In my view this film is the greatest American film of all time.This doc throws some interesting perspectives on the film and is fascinating to watch. I was 17 when I first saw it and pining for a girl I couldnt have. I had total empathy for Jack Lemmon and was cheering for him at the end. Shirley Maclaine was gorgeous. Interesting that Wilder was a refugee from the Nazis. I wonder how many more geniuses were lost ?
