Sir Peter Jackson has decided that the part in The Hobbit where the dwarves are floating in barrels is to be shot near Blenheim, for over ten days in December. 

         Major preparation is to start on October 31, while the scene is to be shot from December 6 to December 16.
Hey, everyone! 
I was just reading an article on, and discovered how Mr. Wood will make his appearance in the Hobbit! He will be in the opening sequences and I quote here from TORn: 

"The fictional book and, either the telling from it or the reading from it, will establish Frodo in the films experiencing Bilbo's story. Viewers are to learn the tale of 'The Hobbit' as a familiar Frodo gets the tale as well. 
Since the speculation is now everywhere around the interwens, TORn can confirm that as of now, the plans are to feature Frodo in the opening sequence of the films."
