"Bob Dylan", or just Harvey in a skinny suit?

I've read this on twelve blogs today, most recently The Reeler: Bob Dylan is trying to get an injunction on Factory Girl, The Weinstein Company's Edie Sedgwick biopic, because it portrays a character based on him as having something to do with Sedgwick's drug-fueled death. The producers have said the character, which Hayden Christensen plays in his first post-Skywalker stretch, is a composite of Dylan, Jim Morrisson and Mick Jagger; Bob Dylan's lawyer has seen the trailer, and he begs to differ:

"You appear to be laboring under the misunderstanding that merely changing the name of a character or making him a purported fictional composite will immunize you from suit. That is not so. Even though Mr. Dylan's name is not used, the portrayal remains both defamatory and a violation of Mr. Dylan's right of publicity."

Factory Girl has essentially been in production since the day Edie Sedgwick died, and even though it's due to come out on December 27, everyone says it isn't finished, and most of us who have watched the trailer suspect it won't be very good. I have to wonder: did Dylan's lawyers act alone, or did Harvey call in a favor to buy him the time he needs to abuse director George Hickenlooper into abandoning the project so it can be shelved indefinitely? Stranger things have happened.
