J. R. R. Tolkien made the Hobbit as a book back in 1937. Later on, the book was published as a movie in 2012. The movie is divided in 3 parts, with one year separating the publishing. In the movie, you follow a young Hobbit, Bilbo Baggins. As he is set out on an "unexpected journey" (Which is also the title of the first movie,) to the Lonely Mountain with a very spirited group of Dwarves to reclaim their stolen mountain home, from a dragon named Smaug. The group has company by the wizard Gandalf the Grey, and Bilbo finds himself joining a company of thirteen dwarves led be the legendary warrior, Thorin Oakenshield. The journey takes the little group deep into the wild. On their way they march through treacherous lands swarming with Goblins and Orcs, deadly Wargs and Giant Spiders, Shapeshifters and Sorcerers. Although their goal lies to the East of the Lonely Mountain, they must first escape the goblin tunnels, where Bilbo meets the creature that will change his life forever, Gollum. Deep down in the bottom of the lonely mountain Bilbo is trapped with the creature Gollum. The unassuming Bilbo Baggins has not only discovered a courage that even surprises him, he also gains Gollum’s “precious” ring that holds unexpected and useful powers.
If you compare the movie and the book, you will discover a lot if comparison and you can see all the red lines pulled together towards a very exciting adventure. The book and the movie have the exactly same intro, and give the viewer a good look into the world of hobbits and norms and values for a hobbit. The Hobbit is a predecessor to the trilogy Lord of the Rings, and you can easily find comparison between those two films.
