What books/stories have you seen turned into movies or plays?

One of my favorite books is "The Wizard of Oz". This book has been made into both a movie and play. I would have to say I liked the play the most. It is based off of the view point of the wicked witch. You see that she wasn't always a wicked witch. She was actually good and became "wicked". The book and movie differ from the play in that the views points are from different characters. I enjoy the play and movie more because you can see what is happening in the story. While reading a book, the reader has to picture what is going on through the words of the author rather than actually seeing it.
