One; Mick Jaggar isn’t really a smoker is he? He never seemed to inhale during the movie even though they had him pretty much chain smoke the entire film.
Two; In the movie, Byron (played by Andy Garcia) already wrote the book and submitted it to his editor. It gets rejected. He then pretty much re-writes the same book with Alcott expecting to get 30% of the cut and half the writing credit. Then Alcott’s wife yanks the carpet out from under Byron after Alcott dies. Couldn’t Byron have submitted for evidence credit for the material since his editor basically already read the book the year before? Proof that he wrote Alcott’s book, I think, and he should have had no problem getting a court order to that effect.
