In 1981 came the second episode of the Star Wars saga, The Empire Strikes Back, directed by Irwin Kerschner. In ESB the rebels visit exotic planets like the ice world of Hoth, the gas giant Bespin and Yoda's homeplanet Dagobah.
These awesome pictures below shows the new scenes. From left to right: 1. A daytime view from Bespin, check out the atmosphere in this picture. 2. Cloud City at dusk, hmm...yummy! 3. A view at a square with lots of people. This one was the BOMB! 4. This is a footage from when the Millenium Falcon first approaches Bespin.
My personal opinion is that The Empire Strikes Back is the best one of the special editions. When you see the new Bespin scene you will understand that the guys at ILM are creating magic.
