Bob Dylan is seeking a court injunction to prevent the release of the Sienna Miller-starring biopic 'Factory Girl', over concerns that the film defames him.

The injunction is said to be based around a false implication that Dylan was responsible for Edie Sedgwick's suicide after jilting her.

Sixties 'It girl' Sedgwick died of a barbiturates overdose in 1971, aged 28.

The Californian heiress was the troubled muse of artist Andy Warhol, whom she met in 1965, and starred in many of his films.

The character that Dylan has issues with is called Danny Quinn and the part is reportedly a mix of him, Jim Morrison and Mick Jagger.

"You appear to be labouring under the misunderstanding that merely changing the name of a character or making him a purported fictional composite will immunise you from suit," Orin Snyder, Dylan's lawyer, wrote to the filmmakers.

"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."

Synder has demanded a halt to all distribution and screenings of the film, which is due to be released in the US later this month.
