Speaking to Julie Andrews in person is exactly like talking to a hybrid of Mary Poppins and Maria von Trapp -- particularly when she tells you in a tempered English accent that the most important thing you can do for yourself is to "let your sparkle out." That advice comes with all the authority and love of a spoonful of sugar. At age 76, after making more than 30 movies, Andrews is now writing a series of "Very Fairy Princess" children's books with her daughter Emma Walton Hamilton.
