Every time there’s a magical film made, it’s a kind of miracle. But the truth is, major talent and huge amounts of sweat were expended to produce this great Hollywood classic. Betty Comden and her husband Adolph Green fashioned an ingenious satire about the transition to sound movies from a book of old songs by producer Arthur Freed and Nacio Herb Brown. Gene Kelly worked himself – and everybody else – to the bone (literally, their feet were bleeding after rehearsals). And the performances by everyone, singers, actors and dancers are extraordinary. If films are about great moments, then this one is full of them. Sublime.
