It's Tolkien Week, cluminating on Saturday 22 September with Hobbit Day - if you don't believe us, just ask Peter Jackson. The director of the Hobbit trilogy will be celebrating on Wednesday by releasing a trailer for the first movie, and new stills are already available.

Take a look below at the latest shots from the film, as premiered by USA Today, and watch Jackson's message to fans ahead of the trailer's launch.

The Hobbit Bilbo Baggins (Martin Freeman) decides to go on a perilous journey with a group of dwarves to reclaim a treasure stolen by the dragon Smaug...

Meet Bombur (Stephen Hunter), Ori (Adam Brown), Dori (Mark Hadlow), Nori (Jed Brophy) and Gloin (Peter Hambleton).

Gandalf the Grey (Ian McKellen) is a less regal wizard than his Lord of the Rings incarnation Gandalf the White.

Thorin Oakenshield (Richard Armitage) is set on reclaiming the Lonely Mountain from Smaug.

Smeagol, aka Gollum (Andy Serkis), is corrupted by his desire for The One Ring.

The wizard Radagast the Brown (Sylvester McCoy) is mentioned only in passing in Tolkien's book but is a fully-realised character in Peter Jackson's film.

Gandalf - they don't call him the Grey for nothing...
