Lucas never completely drops an idea - he merely files it away for possible later use. I thought it might be interesting to discuss all the instances of Lucas delving back into his "dropped concept files." Here's a few I know of: -Cloud City was originally going to have aliens called the Whatnots, who attack our heroes. From SW The Annotated Screenplays: "The notes indicate that the aliensx should be semistoic creatures, sort of tall, think, white, maybe similar to the aliens in Steven Spielberg's Close Encoutners of the Third Kind (1977). They should be very noble but threatening; they carry a spear or a pneumatic dart gun or a long pole with a beam that comes out of it. There's an alien chief described as fair, wise, and noble." Sounds just like the aliens of Kamino to me. When Lucas told his concept artists how he wanted the Kamino aliens to look, they were rather surprised, (as described in the Art of Episode II). They really shouldn't have been, though, since that idea had existed for about 20 years. -The flying creatures that the Kaminoans ride went through several unused incarnations. They were originally developed to be on Bespin. Later, they were going to be used by the Gungans in TPM. Both of those concepts were dropped, only later to be used for Kamino. -The name Mace Windy appears in early drafts of ANH, obviously inspiring the name Mace Windu for the PT. -In the revised rough draft of TPM, Naboo is called Utapau. This was actually the original name of Tatooine in the early drafts of ANH. I really hope we see this name by the end of the saga. It's almost as if it's Lucas's default planet name, and then when he thinks of a better one, he drops it.
