From her days as a youthful minx at Metro Goldwyn Mayer to her post-studio reign as America's lustiest middle-aged movie queen, Taylor has defined the very essence of Hollywood stardom. ''How to be a Movie Star'' is a different kind of book about Elizabeth Taylor: an intimate, up-close look at a girl who grew up with fame, who learned early - and well - how to be famous, and how that fame was used and constructed to carry her through more than sixty years of public life. Indeed, one might say Elizabeth went to school to learn how to be famous, her education courtesy of Metro Goldwyn Mayer, the greatest, most glamorous movie studio of all time.
