In this thread, I'd like for everyone to contribute any dialogue from the OUT alluding to events which took place in the PT era. I want to see what, if anything, mentioned by the characters in the OUT matches what took place on screen in the PT - and if what the character said could have been incorrect by interpretation, rather than by fact.
Obi-Wan, of course, is a treasure trove of information in SW:
"I haven't gone by the name 'Obi-Wan' since, oh, before you were born."
Not literally true, but basically true. When he goes into hiding, there are only a few people throughout the galaxy who know his real name, so I don't think this is contradictory.
"[The Force] is an energy field, created by all living things. It penetrates us, surrounds us, binds the galaxy together."
True. The omission of midichlorians in this description doesn't alter the nature of the Force.
"Your father wanted you to have this [lightsaber] when you were old enough, but your uncle wouldn't allow it."
!? Now, Obi-Wan describes Anakin as a good man, though we saw precious little evidence of this in the PT. But let's take OWK at his word - maybe Anakin's goodness didn't take place during screen time. I think that the good man Anakin Skywalker used to be would definitely have wanted his kid to have his old lightsaber. The only thing that cheapens this (again, referring back to the clumsy PT) is that apparently, the Jedi didn't put a whole lot of time and care into lightsabers; you need one, you just go get a new one. Had the crafting of a new lightsaber been portrayed as a big deal in the PT, then Luke receiving his father's lightsaber would have indeed been an honor; for all we know, this was a replacement unit from the back wall of the Jedi warehouse.
"[Uncle Owen] didn't hold your father's ideals - he thought he should have stayed behind and not gotten involved."
For that matter, Padme didn't hold Anakin's ideals - Anakin belived in the idea of a benevolent dictatorship. I know that isn't what OWK meant - he was, I think, literally describing Anakin as an idealist, which as portrayed he most certainly was not.
It sounds like a serious family conflict if Obi-Wan remembers it so well - almost as if it should have been shown in the PT...
Princess Leia refers to some recent galactic history:
(to Obi-Wan) "Years ago, you served my father in the Clone Wars."
Really? And was Bail Organa was a Jedi General? For all I saw, there wasn't a plurality of Clone Wars - just one. It's like WWI and II - yes, Germany was on one side and the US on the other (extremely simplified version here) in both cases, but no one would call those two distinct events The World War. Similarly, just because the Clone War took place for many years across several planets, one cannot call it "The Clone Wars". I'd like to call this factually incorrect information, but Princess Leia is a diplomat, a whip-smart one; I doubt she would be badly informed here. I therefore have to believe that the original conception of the Clone Wars was not a single war, but several.
From ESB, Obi-Wan directs Luke to the Dagobah system:
"There you will learn from Yoda, the Jedi Master who instructed me."
Had he finished that sentence with "...when I was a youngling.", I have no problem with this.
Yoda and Obi-Wan discuss Luke's potential:
-"You are reckless!" (didn't he mean, "Reckless, are you!"?)
-"So was I, if you'll remember."
I don't remember even a hint of reckless Obi-Wan. He hated flying, he did everything he was told, he was unwaveringly loyal to the Jedi Order. Maybe Obi-Wan was remembering Qui-Gon's attitude as his own, but one would assume that a Force-ghost would have a rather good memory.
More to come, but this is a rather enormous wall of text already so I'll stop.
