I'm Not There - The Bob Dylan Movie

This movie, scheduled to be released in September, is one I am very curious about. I have no idea what to make of the description.I heard about it last year, whereas different actors would be portraying Bob Dylan at different stages in his life. One of those actors would be Cate Blanchett. Um, ok. I think I know where they're going with this.

But here some of the plot outline from IMDB.com:

Formerly going by the title of "I'm Not There: Suppositions on a Film
Concerning Dylan", this is a film about the life of Bob Dylan. The film follows
seven characters, each embodying a different aspect of Dylan's life story and
music.

The film is about the life of Bob Dylan's early days as a struggling
folksinger, the rise to the forefront of the early-'60s folk scene, the
controversial switch to rock, the motorcycle accident and the subsequent retreat
from public view, and the latter-day de-emphasis of recording and concentration
on the concert series known as the Never Ending Tour.

Each story expresses an aspect of Dylan's mercurial personality and each
story is to be filmed differently, in a style appropriate to its theme: Woody
(Franklin) - an 11-year-old black boy, always on the run; Robbie - a womanizing
performer, always on the road; Jude (Blanchett) - the young androgynous rock
star; John/Jack (Bale) - a folk idol who reinvents himself as an evangelist;
Billy (Gere) - the famous outlaw, miraculously alive but growing old.

And each actor is credited playing Bob Dylan, but as... another person?It seems it could be an original, suprising film that could work. Or it could fall flat.Until it comes out - here is a preview of Cate Blanchett... as Jude/Bob Dylan... and David Cross as Alan Ginsberg!
