IGNFF: Now, also the story has arisen that George had always intended prequels, but had never intended sequels to that initial three films.
GARYKURTZ: After this idea of more films came up, he did several interviews where he said he had story material to do nine films: three prequels and three sequels. That was the accepted story, basically, and there was quite a bit of material both before and after the Star Wars lump. So there was no decision to do either one... it was kind of a red herring in a way, because there was no immediate thought to make any other films right away. In a sense, through a business point of view, it probably would have been better to do so, like they did with Star Trek, rather than wait all this time, because the audience interest dissipated somewhat. I mean, it didn't seem to affect the box office on Phantom Menace too much, but ...
IGNFF: It didn't exactly leave a good taste in people's mouths, either.
KURTZ: Well, regardless of the value of the film as a film, artistically, there is a kind of energy around some things where if it had come out say three, four years later after Jedi, and then another one three or four years later after that, that kind of cycle would have probably been better for the audience and for the merchandising than what happened. But that's hindsight. At that time, he always said that he had enough material for three earlier films and three later films, to make a total of nine, and there were outlined materials certainly for a later three that culminated with this big clash with the Emperor in Episode IX. So, we'll never see any of those, based on what he's said now.
