Oh, Tack, IIRC Lucas didn’t type up his own scripts for SW 1977; his secretary, Debbie Fine, did.
I recall reading a quote from her complaining about Lucas spelling the same alien names “five or six different ways” one each page. A bit hyperbolic, but somewhat true – evidently GL was trying out different ways of spelling certain phonetic names as he wrote. Fine’s job included proofing the spellings for consistency, but she didn’t always catch everything (see “Youreallians” vs. “Ureallians” for Han Solo’s species in the 1974 rough draft).
Wow. What an unsung hero. I applaud you, Ms. Fine (wherever you are).
