The Hobbit is a film series consisting of three high fantasy adventure films directed by Peter Jackson. They are based on the 1937 novel The Hobbit by J. R. R. Tolkien, with large portions of the trilogy inspired by the appendices to The Return of the King, which expand on the story told in The Hobbit, as well as new material and characters written especially for the films. The films are subtitled An Unexpected Journey (2012), The Desolation of Smaug (2013), and The Battle of the Five Armies (2014
The screenplay was written by Fran Walsh, Philippa Boyens, Jackson, and Guillermo del Toro, who was originally chosen to direct before his departure from the project. The films take place in the fictional world of Middle-earth sixty years before the beginning of The Lord of the Rings, and follow hobbit Bilbo Baggins (Martin Freeman), who is convinced by the wizard Gandalf the Grey (Ian McKellen) to accompany thirteen dwarves, led by Thorin Oakenshield (Richard Armitage), on a quest to reclaim the Lonely Mountain from the dragon Smaug (voiced by Benedict Cumberbatch).
The films also expand upon certain elements from the novel and other source material, such as Gandalf's investigation at Dol Guldur, and the pursuit of Azog and Bolg, who seek vengeance against Thorin and his ancestors.
