 Brackett finished her first draft in early 1978 ; Lucas has said he was disappointed with it , but before he could discuss it with her , she died of cancer . With no writer available , Lucas had to write his next draft himself . It was this draft in which Lucas first made use of the " Episode " numbering for the films ; Empire Strikes Back was listed as Episode II . As Michael Kaminski argues in The Secret History of Star Wars , the disappointment with the first draft probably made Lucas consider different directions in which to take the story . He made use of a new plot twist : Darth Vader claims to be Luke 's father . According to Lucas , he found this draft enjoyable to write , as opposed to the yearlong struggles writing the first film , and quickly wrote two more drafts , both in April 1978 . He also took the script to a darker extreme by having Han Solo imprisoned in carbonite and left in limbo .
