Deliberate mistake: When Bilbo finds The Ring, he kneels down to get it. In the prologue in Fellowship Of The Ring, Bilbo is lying on the ground. The direction he looks toward when he overhears Gollum is also different.
The Hobbit: An Unexpected Journey (2012)
1 deliberate mistake
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: In the film, Gandalf tells the dwarves he chose Bilbo because hobbits are light on their feet, and because Smaug would not recognise the scent of a hobbit as he would a dwarf. Also Bilbo is the most adventurous of the hobbits in the Shire. This reason is not in the book but is from the story "The Quest of Erebor" in Tolkien's Unfinished Tales.
