1 video
Directed by: Peter Jackson
Starring: Ian McKellen, Martin Freeman, Andy Serkis, Richard Armitage

Continuity mistake: Just after Radagast has a flashback of him seeing the Necromancer, some of the white stuff on his beard disappears briefly in the shot where he inhales the stuff in Gandalf's pipe. (01:15:20)
Bilbo: Oh, up to but not exceeding one fourteenth total profit if any. Seems fair. Present company shall not be liable for injuries including but not limited to laceration, evisceration... Incineration?
Bofur: Oh, aye. He'll melt the flesh off your bones in the blink of an eye.
Balin: You all right, laddie?
Bilbo: Yeah, I'll be. Feel a bit faint.
Bofur: Think furnace, with wings.
Bilbo: Yeah, I-I-I need air.
Bofur: Flash of light, searing pain, then poof, you're nothing more than a pile of ash.
Bilbo: [Long pause.] No. [Bilbo faints.].





Answer: Gandalf has already convinced the dwarves Bilbo is a burglar and Bilbo realised he needs a lot to convince them otherwise. Bilbo is also intimidated by Gandlaf and confused about his claims so he is not sure how to handle the situation.
