TORn reports that New Line has recently registered two film titles, which may be the titles of the upcoming two-part project. The titles are:
The Hobbit: There and Back Again and The Hobbit: An/The Unexpected Journey.
No confirmation from Warner Brothers/New Line/MGM, but the titles certainly seem plausible. Whatever the films end up being called, ‘Part 1’ is expected in theaters in December 2012 followed by Part 2 in December 2013.
