Mrs. Cameron's Favorite: "It’s Chevy Chase from Caddyshack.”

An unbylined AP story relayed this story of the Prime Minister's wife, here with her husband to attend various functions, including Wednesday's state dinner where George Clooney and Rory McIlroy were guests.

David Cameron revealed at a luncheon that his wife was thrilled to learn that her favorite movie star was coming.

“I said, ‘Is it Ben Kingsley from ‘Gandhi’ or Peter O’Toole from ‘Lawrence of Arabia?’” Cameron said.

“No, it’s Chevy Chase from ‘Caddyshack,’” Cameron said his wife had told him.

But it turned out the only Chevy Chase on the invitation list was the Washington suburb of Chevy Chase, Md. — the home address of one invitee.
