I guess I’m in a minority...but with a good story, I still feel like I don’t care WHO plays Indy, as long as it’s a good story. I view it like James Bond...there are several who have been stellar, and some who weren’t as good...but the fact that Daniel Craig and Sean Connery have both played the same character doesn’t make me enjoy either of their films in the role any less.
Heck, they could even play it up a little bit by having Ford in the film, as Old Man Indy, recounting a tale from his youth.
University Student: Dr Jones, is it true you were once on the cusp of finding the Lost Treasure of McGuffin?
Harrison Ford as Old Man Indy: Yes, but that was a long time ago, kid.
Student: Well, I’ve got time.
Old Man Indy: Kid, at my age I don’t know if I can even remember...things start to get hazy, names, faces...
Cut to an obviously young Indy getting punched in the face. When he pops back up into screen, it’s Chris Pratt (or whoever else you fancy as an Indiana Jones) and the story goes from there.
It’s not so much a reboot as a passing of the torch, and if the film is good and the story is good, nobody will forget that Ford was Indy, but they’ll have a new Indy to enjoy, as well.
I don't know...maybe it’s just me, but I think that would be pretty cool. It also gets Indy back to the era he belongs in.
