The Hobbit is scheduled to be released in two film installments, this winter and next year.

Peter Jackson—Oscar-winning director of the Lord of the Rings film trilogy—recently completed filming his follow-up project, the film adaptation of The Hobbit.

His plan is to split the book into two movies: An Unexpected Journey will come out this December, and There and Back Again is scheduled for release in 2013.

At last week’s Comic-Con in San Diego, Jackson showed lots of footage from the two upcoming films. In fact, GalleyCat speculates that he probably has enough material to extend the project into a trilogy—though Deadline reports that Jackson has already stretched the plot of the novel to fill out two movies.

In addition to the original plot, Jackson delving into 125 pages of notes that J.R.R. Tolkien appended to The Return of the King that flesh out details of the story, such as what Gandalf is up to during his absences in The Hobbit. In fact, Tolkien himself planned to use those notes to rewrite The Hobbit, tying it more closely to the mythology of the Lord of the Rings trilogy.

Jackson showed more footage of his upcoming films than any other project at Comic-Con, with the exception of Dredd, which was screened in its entirety. He presented twelve-and-a-half minutes from the movies themselves, as well as fifteen minutes of behind-the-scenes footage. Much has been made of his decision to shoot in 3D, and at 48 frames per second (fps), rather than the industry standard of 24 fps. Some people were disappointed that the Comic-Con presentation was shown in the standard 2D and 24 fps, although the Wall Street Journal reports that the screening received a warm reception from the crowd, many of whom had camped out in front of the hall.

For anyone who didn’t make it in, New Line Cinema has posted several behind-the-scenes videos on its Facebook page, from the set of the films.
