Z dweller said:Personally, I don't feel another movie with Ford is necessary or desirable at this stage, in fact I'd have been happier if Disney had recast the character in Indy 5.
But I'm still hoping we'll get some flashback scenes set before TOD in the timeline, with a younger actor wearing the fedora.
I'm happy we're getting an Indy 5 (and pleasantly surprised it's a true sequel with Ford) but don't have any preconceived notions for where it should go beyond that. I grew up with the original films which means I also grew up in an era when franchises were allowed to run their course and give way to new properties. It's one reason we're currently posting on an Indiana Jones fan site as opposed to one devoted to Tarzan of the Apes.
That said, I agree with you that the simplest way to introduce a new actor would be to take the LC route: A prologue with a younger actor, assuming that a rebooted sequel was planned to follow soon after. But this is clearly not what Marshall or Spielberg have in mind or they wouldn't keep doubling down on Ford being the only actor in the role.
As Udvarnoky said it makes for a fascinating question: How do you make full use of the Indiana Jones brand when you don't plan on using Indiana Jones after one or possibly two films? It's one of the more interesting dilemmas we've seen appear in an aging franchise revival.
