But I understood that you thought i was talking from an audience point of view, but it is kind of the only way anyone except George Lucas can view it becuase only George Lucas knew exactly what he thought at the time of writing the movie.
Not if you're talking about analysis of plot structure. If you're a first-time viewer, then, sure, you're not going to know the twists and turns or surprises. But in order to properly analyze how a story works, you do have to know everything in context and place that information back where it belongs.
But the way i read the script of ESB and understood it is that, its like a cliff hanger......is he or isnt he???? and a tacked on one at that... it would still have been a great action movie with out the father son thing...however adding that thematic element later on proved to be a good idea ...as it gave the movie a whole new dramatic edge to it. Poor old George still didnt know what he was gonna do with the next movie tho.
Yeah. He did write it in a way that leaves it open enough for ambiguity that he could have abandoned ship in the next film if he'd wanted to, no question, but I'm not sure where you're going with that. Even if we are to assume that the movie was written to be teetering on the brink of one or the other, with one as potentially valid as the other, the fact still remains that one side is ultimately chosen and the other discarded. It's not like the original Star Wars where the father interpretation doesn't exist at all.
So to sum up finally, I don't think the way it is written you can assume darth vader is anakin skywalker - and it was only a handfull of scenes that were added into the movie to insert the father son story - I dont think the movie was re-written when George Lucas got the idea he just added a few more scenes to put it in there.
Well, here's where we disagree. It seems we both agree that George Lucas, as a writer, has hack-like tendencies and often screws himself over in his ability to properly plot. But you seem to think he's so much of a hack he would just throw in a major plot element without bothering to rewrite the rest of the script to accommodate that? ... Come to think of it, if we were talking about Revenge of the Sith, you'd be proven completely correct, as he did do exactly that. But in ESB-era, Lucas was surrounded by intelligent people and co-writers, and, by looking at the scripts, you can see that he did alter things for this new context. I mean, it's not like he had any scenes on Dagobah where Luke talks to the ghost of his dead father... which were indeed in the first draft. It was actually quite early on that he came up with the idea, after Leigh Brackett's first draft.
So, yeah, while my opinion of Lucas is quite low, my opinion of Lawrence Kasdan is less so. So even if we do accept that Lucas was so poor a writer he didn't bother to adapt his story for an entirely new context, it's impossible to even suggest that Kasdan would not have had all the appropriate knowledge in his head before he sat down to write the actual screenplay. So, yes, that context would had to have been there throughout.
