<P> Film historian Laurent Bouzereau notes in his 1997 book Star Wars: The Annotated Screenplays that in the rough draft of Star Wars, Leia is the spoiled teenage daughter of King Kayos and Queen Breha of Aquilae, with two brothers, Biggs and Windy; Biggs returned to the fourth draft as a childhood friend of Luke . According to Skywalking: The Life and Films of George Lucas (1999), Luke Skywalker was originally Luke Starkiller and Leia was "the daughter of Owen Lars and his wife Beru and seems to be Luke's cousin--together they visit the grave of his mother, who perished with his father on a planet destroyed by the Death Star ." J.W. Rinzler explains in The Making of Star Wars: The Definitive Story Behind the Original Film (2007) that a later story synopsis establishes Leia as "Leia Antilles", the daughter of Bail Antilles from the peaceful world of Organa Major . In the fourth draft it was established that "Leia Organa" came instead from Alderaan . </P> <P> Fisher was 19 when she was cast as Princess Leia, with actresses including Amy Irving, Cindy Williams and Jodie Foster also up for the role .

Asked about Streep in 2015, Fisher said, "I've never heard that one . But Jodie Foster was up for it...that one I knew the most . Amy Irving and Jodie . And I got it ." </P> <P> The second draft of the Return of the Jedi screenplay contained dialogue in which Obi - Wan tells Luke he has a twin sister . She and their mother were "sent to the protection of friends in a distant system . The mother died shortly thereafter, and Luke's sister was adopted by Ben's friends, the governor of Alderaan and his wife ." Fisher explained in 1983: "Leia's real father left her mother when she was pregnant, so her mother married this King Organa . I was adopted and grew up set apart from other people because I was a princess ." </P> <P> Composer John Williams created a musical leitmotif for Leia which recurs throughout the Star Wars saga . "Princess Leia's Theme" was recorded as a concert suite (4: 18 length) for the score of the 1977 film . </P>
