Harrison Ford wants to do another "Indiana Jones"
Yes, apparently inspired by his return to the role of Han Solo (and forgetting how bad "Indiana Jones and the Kingdom of the Crystal Skull" was), Ford told Entertainment Weekly that he'd "love to do another 'Indiana Jones.'"
"A character that has a history and a potential, kind of rollicking good movie ride for the audience, Steven Spielberg as a director -- what's not to like?" Ford said.
This isn't the first time Ford stated he wants to do a fifth "Indiana." He told Hitfix in 2013 he'd "be happy to do it" as long as there was a "good script":
As the Guardian points out, Ford isn't the only one interested in this project. Spielberg recently said he had a "fervent hope" he'd get to do another "Indiana Jones" with Ford. And while "Kingdom of the Crystal Skull" left the door very much open for a fifth installment, it looked like Shia LeBeouf would be taking the reins from the aging Ford. Then LeBeouf publicly criticized the film and his part in it, and Ford criticized LeBeouf, and I think it's safe to say we've seen the last of LeBeouf's Mutt Williams.
It's important to note that there's been talk of a fifth "Indiana" for years now, sometimes with Ford in the lead role, sometimes with a younger actor taking it over, and obviously it has yet to happen. And at this point, with Ford pretty much past his action star days (though looking good in what we've seen of "The Force Awakens!") and "Kingdom" being more of a stain on the franchise's legacy than anything else, do you really want it to?
