Here's a clip from the new film on Bob Dylan's life. The film is called I'm Not There and features six different actors portraying Bob Dylan in different stages of his life (Marcus Carl Franklin, Ben Whishaw, Heath Ledger, Christian Bale, Richard Gere, and Cate Blanchett).
In this clip, Cate Blanchett (yes, Cate Blanchett) is Bob Dylan in what appears to be around 1965. It is based on the Dylan we see in D.A. Pennebaker documentary of Dylan's 1965 London Tour, Don't Look Back, only with a rather amusing - though fictional - twist.
How did Bob Dylan meet Alan Ginsberg (who appears in the background in the video - some say, the very first music video - of Subterranean Homesick Blues)?
I'm Not There is scheduled to be released in September.
LATER: By the way, when the "Bob Neuwirth" character says "See you later, Allen Ginsburg," he's alluding to an outtake from the bootlegged (and later officially released) "Basement Tapes" where Bob Dylan and Band are fooling around and singing "See you later, Alligator, After while, Crocodile," and it turns to "See you later, Allen Ginsburg ..."
