As with most Hollywood biopics (particularly back in the 1930s, 40s, and 50s), this account of the life of George Gershwin is somewhat fictionalized. As just one example, in real life he also had two sisters, who are not even mentioned in the film. And, the romantic angles here (with two women) apparently are fictionalized. But, so what. This is a surprisingly entertaining film, and a number of Gershwin's pieces are faithfully executed, including "Rhapsody In Blue". I watched this quite a long time ago and remembered it as one of the better movie biopics...plus, I rather like Gershwin's music. I think I liked this film better the second time around.
Robert Alda is fine in the lead role, as are others in supporting roles, including Charles Coburn as a mentor on the pop side of things. Particularly interesting are the many "cameo" appearances by real associates of Gershwin -- Al Jolson ("Swanee"; although so clearly too old to play a young Jolson!), George White (of the famous "Scandals"), and Paul Whiteman. Supporting players are good here -- Joan Leslie, Alexis Smith, especially Albert Bassermann,
Rosemary DeCamp, Oscar Levant, and Herbert Rudley (as Ira Gershwin).
At just over 2:20, it's a long movie, but that length allows so much of the Gershwin music to be played. I can't help but compare this to the Cole Porter biopic starring my favorite actor -- Cary Grant; but this is so much better a film. A good movie worth watching at least once for the acting and to revel in the music.
