    Who qualifies as a Bond girl has changed over the years, as the

    blue-eyed, buxom blonde has given way to more diverse leading ladies,

    including Michelle Yeoh ("Tomorrow Never Dies") and Halle Berry ("Die Another Day"). Modern Bond girls also present a more formidable challenge to the suave secret agent.
