C3PO

Might I also add how very important nature was in the Original Episodes. Lucas filmed these episodes on various outdoor sets in locations around the world, including: Tunisia, Guatemala, England, Arizona and California. Episode 3 however was done entirely in-studio (see link-http://www.youtube.com/watch?v=-uZH9i3J4rw&feature=related). Not only was it incredibly hard for the actors to perform with nothing to evoke real emotion, I was never given the opportunity to get out and stretch my gold plated legs (Reeves).
More evidence of Lucas using nature in episodes IV-VI can be found in his decision to implement a potato (see link-http://www.youtube.com/watch?v=TKsVVmOGV9I) as one of the asteroids (starwars.com). That is correct, while it appeared that Han was navigating us all through a perilous field of asteroids, it was no more dangerous than flying over Idaho. Lucas also turned to other foods for inspiration. The Millennium Falcon was patterned after the shape of a hamburger with an olive on the side (Lucas).
Due to the lack of nature and overuse of technology the newest Star Wars Episodes are far too busy! The backgrounds and scenery of the original episodes are full of scenic skies, natural landscapes, and relatively calm backgrounds. The new episodes contain constant movement and brilliantly colored backgrounds that scream they were technologically enhanced. Take for example these shots from the Original Episode and Episode III. In the Original Episode R2D2 and I are in a wide open area of Death Valley, CA. In Episode III we were simply in front of a blue screen. There is absolutely nothing real about that background. By relying so heavily on computers and technology Lucas lost the forceful effect of reality.
