That may also have been true for Lucas's intentions at the time ANH was made, before he actually had a lot of the rest of the story worked out. A lot of what we're all fussing over may well have initially been throwaway expository lines, that Lucas may never have intended to expand upon back then.I think it is the other way around. At least how it is presented in ANH. She is the celebrity (being a princess and a senator) , and he's just someone who served her father (as a general).
She does not seem to know that he is/was a jedi in ANH ... if they wanted his help because of his jedi abilities she should have addressed him as a jedi instead of as a general.
Still, because of the circumstances she's begging him for help desperately. She's basically betting on his loyalty and compassion, mentioning how he served her father, how this is very important for the rebellion, etc. I really find it hard to believe that if he saved her life 9 years ago she won't use that to strengthen her message. Like "You saved me from the empire when I was kidnapped, now I need your help again. .. blah .. blah... Help me, Obi-Wan Kenobi, you are my only hope"
None of that changes the facts that Lucas did re-work his story as he went, throughout the OT and PT, and left plenty of loose ends to potentially tie up in ways that Lucas either never thought through, or never delivered upon if he did. The PT would seem to dictate a lot more than any of George's original intentions back in '76, that evolved and changed dramatically over the following 30 years. Lucas seems to get a pass for this, but Disney does not?
So, if that is how Leia's lines in ANH could be theoretically improved to better mesh with the Kenobi show that we got, the question becomes what story changes for the Kenobi show might have worked better for the actual lines that we got back in '77? Can you have young Leia meet Kenobi at all before ANH, or do those ANH lines preclude any such possibility, as some seem to be arguing?
