Directed by: Peter Jackson
Starring: Ian McKellen, Martin Freeman, Andy Serkis, Richard Armitage
Continuity mistake: In the scene where Bilbo, now invisible, sees Gandalf and the dwarfs run past the cave and he can't join them because Gollum blocks the way. When Bilbo finally runs past Gollum and kicks him in the face and knocks him down, the very next shot shows Gollum's body lying in the opposite direction, away from the direction Bilbo kicked him. (02:19:35)
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.
