Given that Rankin-Bass was able to cover most of the novel's high points in under 90 minutes in the 1977 animated adaptation of The Hobbit, A viewer might ask how could a mere third of the book stretch to 169 minutes in the first installment, The Hobbit: An Unexpected Journey (Science 2 )? The answer to this is that Jackson is merely an amazing man of detail
It seems as if he uses the book to create the movie based on every word that the author has set (Nuwer 1). Although he did leave out some information, one could speculate that from the time this book was written circa (1937), and now (2000s) the filler between some of the book and the movie would have to be cut (Lotr 1). The film takes its time with the backstory that brings 13 rambunctious dwarves led by Thorin Oakenshield to acquire "young" Bilbo Baggins for a quest to reclaim the dwarf treasure stolen by the dragon Smaug. The film takes any hint of combat or action from the books as an opportunity to flesh out a full-on battle sequence, and stories the book covers briefly or offscreen (Robinson 1).
Although it may seem like the main character is his antagonist mainly because of his timidity, complacency, and uncertainty work against his inner strength and heroism.For both the movie and the book one could see that they both shared the same major antagonist. In the book The Hobbit, Smaug is the dragon of Lonely Mountain and the antagonist of the tale. He is the feared end of the journey. Although he is not present for most of the story, his existence looms. His attack on Lonely Mountain displaced an entire people and several towns. Before his death, Smaugs conversations with Bilbo expose him as an arrogant and hateful beast who loves treasure only for the sake of having it so, in the end, the antagonists remains to be him (Tolkien).
From both sources, we see that amazing attention is spent on the dialogue. Jackson effortlessly incorporates many of the conversations in Tolkien's book to the tee.
