Sienna Miller was cast twice as Edie Sedgwick. She was dropped by the producers because they felt they needed a "bigger name." Miller was eventually re-cast in the role, due in part to massive publicity from her public break-up from fiancée Jude Law.
The first film Andy gets Edie to appear in with Gerard Malanga and the all male cast is Andy Warhol's interpretation of the novel 'A Clockwork Orange'.
Why is Hayden Christensen's character listed as "Musician" and no longer as Billy Quinn?
A
It is because Bob Dylan threatened to sue because it looked like it was his fault Edie died. That's what the trivia says anyway.
Q
What are the differences between the Theatrical Version and the Unrated Version?
A
For the home theatre market, an unrated version was released aside from the R-rated theatrical version. Most scenes which were re-inserted or alternately shifted, serve to specify character drawings and various aspects of the story which were only embedded in the theatrical version to some extent. However, there are also a few extensions with sexual contents and more explicit depictions of drug use. A detailed comparison between both versions with pictures can be found here.
Q
