One thing I noticed in reading the comments of this movie is that nobody recognized the screenplay by Betty Comden and Adolph Green. Without their screenplay the movie does not get made. It is a great script that was made better by Gene Kelly and Stanley Donens' fluid direction. Everything in this movie glides effortlessly. Throw in dancing by Donald O'connor, Debbie Reynolds, Cyd Charisse and of course Gene Kelly, Great songs and the willingness of producer Arthur Freed to let the creative people to do their thing and you have a classic.
