We’ve been talking about a fifth Indiana Jones movie since 2008, but now that Jurassic World – the revival of another ultra-successful Steven Spielberg-led franchise – is the biggest film of 2015, we’re really talking about a fifth Indiana Jones movie. Things We Loved As Kids is almost a movie genre in and of itself now, and in the right hands an Indy revival has serious box office potential, but what form will it take?

Harrison Ford is 73, and though he’s still hard at work and willing to commit to blockbusters like Star Wars: The Force Awakens, you have to wonder whether or not he’d still be up for more whip-cracking in the title role. So, with that in mind, rumors have swirled for years that the franchise will continue with a younger actor in the lead. At first, those rumors were centered on Shia LaBeouf, who played Indy’s son in Kingdom of the Crystal Skull, but these days…come on, we all know that’s not gonna happen. The hotter, and seemingly more credible, rumor is that Jurassic World star and relatively new blockbuster force Chris Pratt could put on the fedora, and if not him, then a similar young star could do it, either as a full reboot or a Next Generation kinda thing.

Whatever form it takes, producers have made it clear that Indy 5 is a thing they want to do, but will they do it with Ford or with someone else. Here’s producer Frank Marshall (who worked on all four previous films) in the latest issue of Total Film (via Den of Geek).

“There are a lot of rumours,” Marshall admitted. “We haven’t even sat down to talk about Indy yet… at some point we’ll sit down. But there’s a bunch of people who could probably take the baton.”

OK, so Marshall seems open to a new actor in the leading role. But wait, then he said the filmmakers are “not doing the Bond thing where we’re going to call somebody else Indiana Jones… we have to figure this out.”

So, Marshall is clearly opposed to just grabbing another movie star and saying “Here’s your new Indiana Jones,” but the “take the baton” comment makes it sound like he does perhaps want someone else to lead the new film. So…which is it? Well, Ford’s already clearly playing a kind of mentor figure to a new generation of stars in Star Wars: The Force Awakens, so it’s possible he could do the same thing with Indy. The next Indiana Jones and the… flick could see Ford as a kind of elder statesmen of archaeology adventure, leading another, younger adventurer to glorious treasures. Or, it could mean they’re simply pushing ahead with Ford no matter what. Or, it could be some weird hybrid of the two. We don’t know, but whatever the case, Marshall seems to be set on no one but Harrison Ford playing Dr. Henry Jones Jr.
