The worst thing is there are already two completely brilliant films about Dylan - 'Dont Look Back' and 'No Direction Home'. By all means enjoy your fictionalised nonsense though.
Tommy man, i agree, these are both as good as anyone could want them to be. But have you watched the clips on the links above? personally, i think it looks like they've done an amazing job at offering a fresh, unique interpretation of his life while staying true to his character. Also, if Dylan had been perfect throughout his career, both personally and on record, he wouldn't be worth making such a film on. What makes Dylan so interesting is that he was and is a highly flawed character, he was endlessly developing and getting bored with and reiventing his style, and it looks like this is what this film will try to convey, the conflicts of an artist in conflict with himself and his past- tying at every stage to be sincere and honest to who he was at that time in his life. Also, Don't look back covers on tour in 1965, No Direction Home 1960 to '66- this is the first film to my knowledge to attempt a comprehensive vision of the man.
Before getting so cynical, i reccomend you check out other films by Todd Haines- they are as orignal, well made and enjoyable as films can get, and i would trust this complex figure in his hands. I've liked every thing of his i've seen (and this includes a gay film- and i'm not gay).
