But hell, the book was not smaller? 

It is from this observation that we focused on the adaptation of "The Hobbit" at the movies!

For this Pegi-P reread the book (or at least 60 pages that are present in the first film) and attacked a cut of the film according to the following criteria: 

It is not in the book, I hop the ledge! 
This scene is not in the book, I hop the ledge! 
That is the lord of the rings, I turn hop! 
That it has nothing to do here, I hop turns! 
In the end it emerged from this phase with a clear and precise clean cutting of the first film and LF were able to attack the installation. 

In the end the film lasts 1:30, half time base film!
