Lord of the Rings, be it the book or the movie version have in recent times, gathered a lot of attention, especially from the movies that have come out as sequels to the the 3 series LOTR.
The Hobbit as a book, came before the Lord of The Rings series and even though it is one single books, in the movie version it has been broken down into three distinct parts with The Desolution of the Smaug being the second in the series and the last yet to be released.
In the second movie of the Hobbit series, we find a number of things that can be very easily represented numerically, for instance, there was on dragon and one hobbit, but two wizards- Gandalf and Radagast.
Also, when you look into the process of the making of the movie you find that almost 10 kgs of human hair was required for the wig-making and it took almost 752 wigs for almost everyone can be found in wigs here.
