Sienna Miller Smoking In Fur

On set for her latest film Factory Girl, Sienna Miller is in New York and still working towards the wrap. What is this flick about, you ask?

A beautiful, wealthy young party girl drops out of Radcliffe in 1965 and heads to New York to become Holly Golightly. When she meets a hungry young, artist named Andy Warhol, he promises to make her the star she always wanted to be. And like a super nova she explodes on the New York scene only to find herself slowly lose grip on reality…
