British actress Emily Mortimer has been ordered to "sex-up" her image - and flash her cleavage in a bid to win lucrative movie roles. The Match Point star claims Hollywood producers warned she will not be a successful actress unless she undergoes a makeover. She says, "I'm constantly being told I'm not sexy enough and I should show my boobs more. I've been told that I've got good breasts and I should make them more apparent when I go into meetings. But I don't suit that sort of thing and can't carry it off. "I've also been told to dye my hair and get my teeth whitened. This is a weird, weird job."
