Production history
Original trilogy

For the second draft, Lucas made heavy simplifications, and introduced the young hero on a farm as Luke Starkiller. Annikin became Luke's father, a wise Jedi knight. "The Force" was also introduced as a mystical energy field. The next draft removed the father character and replaced him with a substitute named Ben Kenobi, and in 1976 a fourth draft had been prepared for principal photography. The film was titled Adventures of Luke Starkiller, as taken from the Journal of the Whills, Saga I: The Star Wars. During production, Lucas changed Luke's name to Skywalker and altered the title to simply The Star Wars and finally Star Wars.[33]
John Williams, composer of the musical scores for all six films of the original and prequel trilogies. At that point, Lucas was not expecting the film to become part of a series. The fourth draft of the script underwent subtle changes that made it more satisfying as a self-contained film, ending with the destruction of the Empire itself by way of destroying the Death Star. However, Lucas had previously conceived of the film as the first in a series of adventures. Later, he realized the film would not in fact be the first in the sequence, but a film in the second trilogy in the saga. This is stated explicitly in George Lucas' preface to the 1994 reissue of Splinter of the Mind's Eye:
It wasn't long after I began writing Star Wars that I realized the story was more than a single film could hold. As the saga of the Skywalkers and Jedi Knights unfolded, I began to see it as a tale that could take at least nine films to tell—three trilogies—and I realized, in making my way through the back story and after story, that I was really setting out to write the middle story. The second draft contained a teaser for a never-made sequel about "The Princess of Ondos," and by the time of the third draft some months later Lucas had negotiated a contract that gave him rights to make two sequels. Not long after, Lucas met with author Alan Dean Foster, and hired him to write these two sequels as novels.[34] The intention was that if Star Wars were successful, Lucas could adapt the novels into screenplays.[35] He had also by that point developed an elaborate backstory to aid his writing process.[36]
Later that year, Lucas hired science fiction author Leigh Brackett to write Star Wars II with him. They held story conferences and, by late November 1977, Lucas had produced a handwritten treatment called The Empire Strikes Back. The treatment is very similar to the final film, except that Darth Vader does not reveal he is Luke's father. In the first draft that Brackett would write from this, Luke's father appears as a ghost to instruct Luke.[39] 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.[40] 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.[41] 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.[42] 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,[43] both in April 1978. He also took the script to a darker extreme by having Han Solo imprisoned in carbonite and left in limbo.[9]
