New York, Jan 10 : Aussie actor Russell Crowe has been throwing his weight around on the pre-production of `Nottingham' so much that Brit actress Sienna Miller has dropped out of the flick.

Crowe is reportedly telling producers to get a new director and demanding script rewrites.

Miller, who was supposed to play Maid Marian, left the production on January 9 after she was put on hold while shooting was pushed back from February to April.

"It is a mess. Russell never lost the weight he put on for ''Body of Evidence'' - and so the love scenes between him and Sienna would have been laughable. He''s so old and fat and she''s so young and gorgeous. It''s just . . . gross," the New York Post quoted an insider as saying.

One producer said Crowe has to shed 35 pounds, adding: "We can''t have Robin Hood looking more like Friar Tuck."

As per reports, producers are looking for an older, plumper actress to play Miller's role to compliment Crowe's plump looks.

Miller's rep said that the actress is "fine" and "about to sign onto two other movies", but did not comment on her dropping out. (ANI)
