The book is so much better then the film.  In the book the nanny isn’t someone who studied business and just happens to fall into this job because she can’t define what she wants to do with her education.  In the book, Annie has had experience as a nanny, and has studied to become a teacher because she loves interaction with children.   In thebook unlike the film, Annie (the Nanny) is from a prominent family and does not live with Mr. and Mrs. X, and Grayer.  She speaks French, and is good at her job.  She is kind and tries to help these people relate to their son.   When she finds out, in the book, that Mrs. X has been filming her behavior for a study she is conducting; Annie tries to talk to her about how she should reach out to her child while he is young and needs nurturing.  It’s a good book, and it does not have all the sappy stuff that you see in the movie.  Mr. X does not hit on Annie in the book, but he does have an interest other then his wife, and Mrs. X does become pregnant.  At the end of the book, you get to see that Mrs. X is making efforts to be with her son more, but you don’t find out what happens between Mr. and Mrs. X. The book ends with the reader being allowed to imagine what will finally happen to all the characters.  The film is predictable and kind of silly.
