Johnson continued: “But that would be really interesting considering the dark side is about self-preservation, trying to find immortality, and the notion that the light side actually got to it through selflessness, what would the dark side version of that look like? There’s so much cool [stuff] to think about if you’re willing to open your head a little bit!”
Of course JJ Abrams is writing and directing Episode IX, so the move will be up to him.
Meanwhile Johnson also spoke about how knowledge of Force ghosts and what they can do has been revealed as the saga has progressed.
He continued: “The truth is, because Star Wars until The Force Awakens has been set in amber and we hadn’t had a new Star Wars movie in 10 years, you forget that they were introducing new Force stuff with each movie, based on the requirements of the story.
“Force-grabbing didn’t come around until Empire [Strikes Back], it wasn’t in A New Hope. Same with Force ghosts.”
Johnson added: “They’d introduce new ideas of what could happen with the Force each time…The one point where we do introduce a bit of a twist in terms of Force ghosts is where Yoda calls down the lightning onto the tree.
“That, I think, is a tantalising hint of the potential of someone who is a Force ghost interacting with the real world.”
