I watched the trailer. Andre didn't convince me in the slightest. I also got the impression that they didn't have permission to use the music. One that I'll miss, I think.
For a real rock biopic/documentary, catch Scorcese's brilliant "No Direction Home" and marvel at the fecklessness of the kids coming out of UK theatres complaining about Dylan's electric sell-out. They were there at the birth of modern music and were too self-absorbed (or something) to realise it. OK, easy in hindsight - but I wonder what they think now. Also a great interview with Joan Baez who recounts Dylan's personal betrayal with painful honesty.
