A trailer for The Hobbit: An Unexpected Journey has been issued a year ahead of its release.
The first part of The Hobbit, a prequel to the Lord of the Rings trilogy, will not be released until 13 December next year. A second episode will appear in 2013.
The BBC reports the trailer shows Martin Freeman in the role of young Bilbo Baggins.
It also shows older Bilbo, played by Sir Ian Holm, telling Frodo in a letter that he may not have told him everything about his adventures.
Andy Serkis makes an appearance as Gollum in the trailer, as does Cate Blanchett, reprising her role as mystical elf queen Galadriel. Sir Ian McKellen returns as Gandalf.
The BBC reports the trailer was one of several released this week for 2012's big films.
A trailer for the next Batman film The Dark Knight Rises came out on Monday.
A pre-trailer tease for Ridley Scott's Prometheus has also been shown. The full cinema trailer is due out on Thursday.
Warner Bros. is the studio behind both The Hobbit and The Dark Knight Rises.
