"otherworldly" is just a nice word for "1920s technology".

Getting closer to reality is a common thread in the arts. As soon as man had a way to move from one-color cave paintings to using colors, he started to use them.

This is the artistic expression that Peter Jackson is going for.

In one of the video blogs he said: "The result looks like where the screen was, there is now a hole in the wall, and beyond that is reality".

Imagine, instead of looking a film of Bilbo, you're transported right there into Middle-earth and it looks absolutely real. Wouldn't that be great? I'm very much looking forward to that experience.
