Cette nostalgique leçon d'histoire recèle les trésors cachés des plus grandes comédies musicales de la MGM ainsi que de nombreux autres extraits merveilleux mais moins célèbres, avec Esther Williams, Jimmy Durante, Eleanor Powell et même Clark Gable chantant et dansant. « Il était une fois Hollywood » est une véritable gourmandise pour cinéphiles et amateurs de comédies musicales.
