>>22086949>What were Lucas' intentions in making those films?Mainly to tell Herberts story in the way Lucas felt they should have been told.
Either Herbert has to admit that he's spoofing reality, at which point Lucas spoofing the same thing means he is not stealing anything, or he can continue on playing the silent game and pretend like it's loosely based on religion as a whole rather than specific persons.
What Lucas did was to distill Dune down to the core people which Dune is glaringly based on without getting too lost in irrelevant headcanon worldbuilding.
What Disney does is to try their best at continuing on the "Disney"-touch of the original SW by honoring the fact that it is an actual spoof of history on par with normal Disney storytelling, as opposed to high-fantasy pretending not to be direct spoofs.
Star Wars is self aware of being a stage-act cartoonesque take on EARTHs history, whereas Dune is meant to be a separate fantasy future.
So to simplify it all;
George couldn't let the slander-adjacent Dune franchise get away with telling the story of Juba II while also pretending like it wasn't doing so.
If the popculture ice was to be broken on Juba II, George Lucas felt he had a responsibility of telling the part of the story that Dune was ideologically and thematically opposed to tell, namely the non-slander part.
The truth is that Juba II descend from a side-switching high politics family whose history has shaped the world.
So much that it has become taboo and near forgotten.
