Kate Winslet is worth £60 million [0 million] to Britain. The “Reader” actress was the first celebrity to be “audited” by the U.K. Film Council, which looked to put a specific value on the country’s creative industries and chose the English star as the first example for her success abroad and public profile.

David Steele, the head of research and statistics at the U.K. Film Council, explained: “When an actor achieves international prominence, they have a general effect of boosting their country of origin that works its way through television appearances, advertising and celebrity news.”

A friend said Kate – who won the Best Actress Oscar for “The Reader” this year – found it “both flattering and very funny.”

The audit assessed salaries, profile and “box-office effect” on tourism and entertainment sales to find the figure, which has been nicknamed “the Winslet algorithm” and may now be used to work out the value of other famous faces, including ‘The Dark Knight’ star Christian Bale and current James Bond Daniel Craig.

Kate, 34, is estimated to have earned £20 million [ million] from her movies since 1995, while the head designer of car manufacturer Jaguar admitted he had Kate’s curves in mind when designing the new XK model.
