Musician Lou Reed has blasted Sienna Miller's new movie "Factory Girl" in which she plays Andy Warhol muse Edie Sedgwick reports Ananova.

Reed, 63, who knew Sedgwick, told the New York Daily News, "I read that script. It's one of the most disgusting, foul things I've seen - by any illiterate retard - in a long time. There's no limit to how low some people will go to write something to make money".

Director George Hickenlooper defended the script saying it was a "complex story about a wonderful young woman". The movie also stars Hayden Christensen while Guy Pearce plays Andy Warhol. Sedgwick died in 1971 from a combination of barbiturate poisoning and alcohol.
