He actually seems to go further than that in the interview, saying that he’s not really interested in creating a world or a universe but rather a 2-hour experience in the theater. I’m actually surprised by this because worldbuilding is to me a key aspect of writing, especially sci-fi and fantasy writing.
Whether or not that’s a valid way of creating a story, it really seems to disregard much of the appeal of Star Wars, which took great pains to create the illusion of a vast universe.
