Sienna Miller turned down the opportunity to play a Bond Girl in Casino Royale, even after being offered the part by new 007 Daniel Craig.
The Alfie star claims she passed on the role because she wanted to establish herself as a serious actress.
Craig and Miller starred together in the British gangster movie Layer Cake and media reports at the time suggested the two were romantically involved.
She explains, "It would have been fun, but I didn't want to do it.
"It would have been great to work with Daniel again though, because he is such a brilliant actor and I'm not surprised at all that he has made such a success of the (JAMES) BOND role."
