There's a short article on CNN.com today (presumably inspired by the release of Revenge of the Sith DVD on Tuesday) about the changes Lucas has made to the original trilogy.
The article touches upon what we discussed in class yesterday - Lucas alters his movies because he wants them to conform to his vision, but fans may like the old interpretation or their own interpretations better. And now modern creative tools allow dissenting fans to do the same as Lucas and alter the movies to make them conform with their own idea of what Star Wars should be.
The end of the article discusses Star Wars as a transmedia property, saying
In fact, some of those stories may not be his, anyway. One of the charms of video games is that the player becomes a character in the story, and technology being what it is, the permutations are becoming endless. So, perhaps, "Star Wars" has become a classic sci-fi multiverse conundrum, with alternate histories and varied points of view.
...Of course, my cynical side is convinced that in 10 years Lucas will make the old versions available for an extra charge. Star Wars Classic, anyone?
