Thank God the film-makers trusted in the power of Gershwin's music to allow almost complete versions of the title composition, and "An American in Paris" to be included in the film - as well as many complete songs. All the music is superbly orchestrated and the songs sung beautifully by a wide variety of artists, many of whom were really the first artists to sing them. The film is excellently directed and photographed, with musical scenes well realised visually. The montage of Gershwin wandering about Paris as we hear "An American In Paris" is excellent - and the use of lights and shadows to film the orchestra playing "Rhapsody in Blue" is magnificent - would that contemporary films of orchestras were this imaginative.
Yes I know it is largely fiction - but so what? This is a tribute, not a documentary. And Alda is fine in the lead, backed by an excellent supporting cast. I loved this film from start to finish.
