Lucas Doesn't Want This One Released.
It's funny. Longtime fans know that there were four original "making-of" documentaries on the Original Trilogy. They were:
-The Making of Star Wars
-SPFX: Empire Strikes Back
-Classic Creatures: Return of the Jedi
-From Star Wars to Jedi: The Making of a Saga
These four never made it further than Laserdisc. They were ignored for the OT DVD release in 2004 and have never had a separate release on DVD like they could have.
The new Blu-ray set has been announced for September. Miraculously, the first three are included! Suspiciously, "From Star Wars to Jedi" is not. It's obvious why. In the interviews, Lucas admits that he didn't settle on Vader as Anakin until after Star Wars(ANH) was released! He had to decide between Vader as Anakin or Vader as Anakin's killer and admits he didn't do that until just before ESB began filming. Yet today, we're told that the "saga" was the "Tragedy of Darth Vader" all along. Right. Maybe the new fans buy that but the older fans know better. He also admits that Yoda wasn't created until scriptwriting for ESB. He mentions the fact that ROTJ was originally going to involve a planet of Wookiees, not the Ewoks. A much better idea. He explains why he changed it to the Ewoks. He even says that too often, special effects are on-screen for too long and cannot substitute for a good story.
All of these admissions would be nothing for most filmmakers. But for Lucas, this would debunk the falsehood he puts out to the kids today of the whole thing being a six-film pre-planned "saga" all along. He probably doesn't like the word "saga" in the title of this documentary for the OT either. Not to mention the use of the old Sebastian Shaw force ghost footage from ROTJ.
He doesn't want this one ever released again. How else can you explain the absence of this one, yet including the other three, while giving us nearly four hours of fans in stormtrooper costumes, spoofs, and the lame "Star Wars Tech". Where's "Empire of Dreams" too? What a shame.
