As part of the 100% Pure New Zealand campaign to promote tourism in the country, Warner Bros has posted a great video below with the actors of The Hobbit trilogy discussing the beautiful land that helped Middle-Earth come to life. I especially enjoyed how in short portions they would show a camera sequence used in the movie with the same sequence as it was filmed highlighting that while the movie had a lot of special effects, the land itself didn't really require any.

New Zealand - Home of Middle-Earth. There are any New Zealand - Home of Middle-Earth in here.
