Behind the scenesEdit
- "A Dock[sic]/Desert (caves) planet"
- ―Ttaz as described in the notes of George Lucas
Ttaz was a planet mentioned during Star Wars: Episode V The Empire Strikes Back story conferences involving executive producer George Lucas and screenplay writer Leigh Brackett that took place between November 28 and December 2, 1977, though it was never implemented into any drafts. The concept might have evolved into Geonosis, a planet that appeared in the 2002 film Star Wars: Episode II Attack of the Clones.
