Your question is whether or not making ANH was a mistake you then stated something about TPM. I am quite confused, so I'll simply answer the poll question and not comment on what you posted. I believe ANH (EPIV) was made originally top be STAR WARS and that's it. It has all the characterisitics that would imply a total ending and a stand-alone movie (except for the fact that Vader got away). First, you'll notice the lack of Imperial fleet (except for a total of three Star Destroyers, two of which may have been repeats) and Rebel fleet (except for a single corvette). You'll also notice that the Imperial insignia is quite different from the other two movies. Granted, it may represent a different pattern completely and, again, granted, TESB has a clear pattern, ROTJ insignia is a blooper, it still shows some...changes. You'll also notice allusions to past situations between Tarkin and the Rebellion, who had apparently been someone very important fighting the Alliance. You'll also notice the subsequent complete lack of mention of Tarkin, which shows that ideas changed quite radically from ANH and TESB. I could go on for quite some time, but I fear I have confused enough people already and, for those I have not, I think I have made my point. I think making ANH first was not a mistake since it was probably meant to be the only STAR WARS movie.
