Timeframes/Accuracy ?
Boy, am I having problems with some of this stuff. George meets Oscar Levant in Max's waiting room. According to Wikipedia (which I know is not always 100% accurate), "Swannee" was published in 1918. Well, Oscar Levant in real life would only have been 12 years old at that time! Instead the 39-year-old Levant plays himself...?
Same problem with George White and Paul Whiteman; they were both much older in the movie than they would have been at the time of meeting Gershwin (obviously). The movie makes it seem like these successful older men are hobnobbing with Gershwin, but in reality (if the story is accurate) they would have only been in their 30's. Wonder why they didn't simply get younger actors to play those guys, too?
Jolson we could get away with; he only appeared in blackface (as I recall) but that covers a multitude of sins.
What's the real deal? Did Gershwin really meet these guys in the 1920s?
Hmmm...upon more digging at Wikipedia, there are lots of holes between the movie and the real-life of George Gershwin. Maybe the movie was a sensationalized account of his life. Bleah.
Ah, the rapier wit of an armless D'Artagnan.
