The first instalment in Peter Jackson's Hobbit trilogy sees Bilbo Baggins (Martin Freeman) forced out of his comfortable, uneventful existence after Gandalf (Ian McKellen) persuades him to accompany 13 dwarves on a mission to recover their stolen treasure.
The first clip sees Bilbo becoming increasingly irritated as more and more dwarves turn up at his home in Hobbiton.
Another clip shows Elrond (Hugo Weaving) handing out swords to the 13 dwarves, which follows an earlier clip in which Gandalf gave Bilbo the elven sword Sting.
The first glimpse of Benedict Cumberbatch's villainous dragon Smaug, who is responsible for stealing the dwarves' treasure, came in a TV spot released yesterday.
Director Peter Jackson and co-writer Philippa Boyens have both recently discussed the casting of Freeman as Bilbo.
