Sienna too young for Maid Marian role

Sienna Miller lost the chance to play Robin Hoods sweetheart in Ridley Scott's new medieval epic - because she's too young.

The actress had been attached to 'The Sheriff of Nottingham' for over a year but when the project went through a rewrite, it quickly became clear she was no longer the right fit - and Cate Blanchett became the new leading lady.
