(CBS News) Julie Andrews has been a star on stage and screen for 60 years, from "Mary Poppins" and "The Sound of Music" to "The Princess Diaries." And that's not all - for 40 years, she's been writing children's books.
The Oscar-winning actress said she came about to write because her children begged her.
"They knew that I loved to scribble, and about 40-something years ago we were all traveling together on a movie. They were bored and we were playing a game together, and it was one of those games where you had to pay a forfeit if you lost - I was the first one to lose!"
And so her new stepdaughter asked her to write a story. "I thought, maybe this is a way to bond a little bit with her and give her a small gift.
And she never stopped writing. "I enjoyed that so much and had the pleasure of having that little book published and I never stopped after that. I loved it so."
The book was "Mandy," published in 1971. Since then she has published nearly 30 booksl Her latest is "The Very Fairy Princess: Here Comes the Flower Girl!" It's part of a series Julia started with her daughter Emma about 15 years ago, about a girl who's convinced she's a very fairy princess, despite evidence to the contrary . . . She's got some sparkle that tells her so."
In addition to her authoring children's books, Andrews says she is happy to have been a part of some classic children's movies, like "Mary Poppins." "I think I'm so lucky because every seven years there's a new generation that wants to see them, I thank heavens! They've had longevity which is not true of a lot of movies. I'm very grateful."
She told Rebecca Jarvis and Jeff Glor that her children's books have "book-ended" her film career, which was brought to a premature end following an operation on her throat that affected her singing voice.
"The voice is pretty nonexistent, excepting my lovely Emma with whom I work on these books. I was moaning and carrying on to her one day about missing singing so much, and she said, 'Mum, you found a different way of using your voice through these books.'"
The "Very Fairy Princess" books have also been developed for stage, with orchestral arrangements and narrator (guess who?). "So, in a way I don't know I would have had this opportunity to create and help produce and sometimes direct if I hadn't had problems with my voice."
