Star Wars and Indiana Jones 4: During a recent interview with MTV, science fiction god, George Lucas, talked about his feelings on all the upcoming Star Wars activity scheduled for the next 12 months, as well what's happening with the next Indiana Jones film...

Don't expect any more "Star Wars" flicks after "Revenge of the Sith" — George Lucas says he's done. RELATED: Katee Sackhoff Hints at 'Unfinished Business' for Bo-Katan in The Mandalorian Season 3

"This was never planned as a nine-episode work," Lucas said. "The media [pounced when] I made an offhand comment, 'It might be fun to

come back when everyone's 80 and do another one of these.' But I never had any intention of doing that."

Lucas said he only decided to do the back-story trilogy — which "Sith," due next May, will cap — because he realized he had already written it in order to tell the story in the first "Star Wars" films. "The original 'Star Wars' was only three films, and that was what it was meant to be," he said. "After a lot of pondering and thought, I went back to do the back story, but that pretty much tells the story. Episode six is the end. There isn't any more to it."

"Sith" may mark the end on an emotional level, too. "All the good guys die," he said, laughing. "And you know, it's pretty dark. It's pretty intense. I'm not sure this one is going to end up a PG like the others were."

That apparently doesn't have so much to do with actual violence — like previous "Star Wars" films, this one will have lots of battles and space action — as with what happens to Padme and the children borne from her union with Anakin Skywalker following their escape and separation. "It's a happy story," Lucas joked.

On what he plans to do after Star Wars...

Having accomplished so much on a blockbuster scale, Lucas said that after "Revenge of the Sith" and his upcoming fourth "Indiana Jones" installment (which he hopes to start shooting within a year), he'd like to return to indie-style movies like his 1971 debut, "THX 1138," which returns to theaters Friday (September 10) with a new director's cut.

"I think I've earned the right to fail," he said.
