 In the first draft of George Lucas (qv) screenplay, the movie was  to open with a huge montage sequence showing the end of various  battles of the Clone Wars on seven different planets across the  Galaxy. Each planet was to be distinctly different from the other  and was described as "Bridge world", "Ring World", "Crystal world"  and "Kelp world" amongst others. This idea evolved into the sequence  where we see various Jedi dying at the hands of the Clones on  different planets. Four planets made it into this montage: Mygeeto  (Crystal world), Felucia, Saleucami and Cato Neimoidia (Ring World).
