I have been privately entertaining a hypothesis that I admit is somewhat goofy but that I find appealing nonetheless.
I think Lucas is clearly uncomfortable with how seriously many people take the Star Wars universe. For a not insubstantial segment of the fan base, the core movies are taken as an equivalent to Holy Scripture. Consider how the hardcore people know which of the comics, novels, games, and assorted ephemera can be taken as “canon” and which cannot. It’s just a movie, for crying out loud: yes, it’s based on ancient mythological structures and thus has powerful narrative resonance, but it’s still just a movie. And the degree to which people have embraced the story and its world is understandably distressing to its creator. (One wonders if Roddenberry had similar feelings about what happened to Trek.)
So my hypothesis is this: Lucas is messing with the movies, creating alternate versions and including elements that remind you it’s just a movie, in order to short-circuit the process by which powerful myth makes the transition into True Scripture.* If there are five or six mutually contradictory versions of a movie’s story, all endorsed by the creator at various points, then no one version can be said to be “official,” which is one step short of “real,” insofar as that means anything in a work of fiction. Lucas keeps saying the previous versions don’t exist and whatever he’s offering at the time is the only one, but most of us have the original trilogy on videotape, thus making the assertions of their nonexistence ridiculous. Lucas may be a lot of things, but he isn’t stupid, and he knows that claim simply won’t fly; the previous versions exist just as much as the new ones, side by side, with all the flaws and divergences that have accumulated over time.
In short: The original vision arrived with startling and powerful clarity, and was a siren call to a generation at loose ends with traditional beliefs; and Lucas, looking ahead to the future, has decided to muddy the waters rather than be held responsible for creating a monster that escaped his control through inattention.
(Of course, differing versions haven’t stopped Christians, for example, for holding up the King James or the New Revised or any of the other varying adaptations of the original ancient Biblical texts as being superior to one another, so Lucas may be trying to divert the Mississippi with a krazy straw, as it were.)
Now, I know this is kind of a far-out hypothesis, and I’m offering it not because I believe it’s completely true but more because I find it interesting and appealing on a certain level, and it’s a lot more satisfying for explaining why Lucas has been doing what he’s been doing to the SW universe than simply concluding that he’s lost touch with reality, which is, to me, the only other rational explanation.
*I’ve been vaguely considering starting a thread to consider which modern-era works of art and fiction are most likely to evolve into full-scale religious phenomena over the coming centuries, using “Star Wars” and this particular take on it as a starting point, but also including Tolkein, Trek, Buffy, the Beatles, and so on. Any interest?
