Audiences around the world are joining Peter Jackson on a last journey to Middle Earth with the release of the third and final "Hobbit" film, "The Hobbit: The Battle of the Five Armies," on December 17.

The film may be the last foray into J.R.R. Tolkien's world for quite some time, since the rights for "The Silmarillion" and other connected works still rest with the Tolkien family.

In honor of the last Hobbit film, here are 50 things you might not know about "The Hobbit: An Unexpected Journey," "The Hobbit: The Desolation of Smaug," "The Lord of the Rings: The Fellowship of the Ring," "The Lord of the Rings: The Two Towers" and "The Lord of the Rings: The Return of the King."
