Tinkering with a beloved book series can be dangerous, but if done well, it can help make the translation from book to theater even better. It worked with the "Lord of the Rings" trilogy ... and so far, so good with "The Chronicles of Narnia" series.

Lewis' book -- was cut out of the final print. However, he hinted that we could see this storyline fleshed out in future films.
