If anyone knows what's going on with the universes of Disney, Marvel, Pixar and Lucasfilm, it's the CEO of all of Disney, Bob Iger. In a new interview, Iger said he expects to make more Indiana Jones movies after part five... but that may or may not include Harrison Ford. "Right now, we're focused on a reboot, or a continuum and then a reboot of some sort," Iger told the Hollywood Reporter in an extended interview. He seemed a bit confused about what the words mean.
"Well, we'll bring [Harrison Ford] back, then we have to figure out what comes next. That's what I mean. It's not really a reboot, it's a boot — a reboot. I don't know."
Iger then said, while he doesn't expect Indiana Jones to be as large of a franchise as Star Wars, they will make more than just the one film. "I don't think it reaches the scale of the universe of Star Wars, but I see making more. It won't be just a one-off."
Cutting through all of that, basically Iger said this: They're making Indiana Jones 5 with Harrison Ford and Steven Spielberg. That's the "continuum". From there, they will try a "reboot", or at least "more" Indiana Jones films.
