This book is full of facts about the movie The Hobbit. It was interesting to go behind the scenes.There were a lot of facts that I didn't know. The reason why I gave this 4 stars is because it had mini biographies of each actor in the movie. Most of them I had never heard, and it left me me bored reading their biographies. Also, because many of these unknown actors play minor characters in the Hobbit trilogy, I kept having to constantly Google their names and their characters to see if they were in the The Hobbit movie or were in the later movies of The Hobbit trilogy. Overall, this is a must read for die-hard fans of The Hobbit, who would like to go behind the scenes. However, if you are not much of a die-hard fan, and just liked the movie as I did, you will be a bit lost and will have to do some research to who these actors and the minor characters are in the movie.
