That's the question we're asking today with news that George Lucas has already come up with a storyline for a potential 5th Indiana Jones film. The Search for Atlantis? The Quest for the Fountain of Youth? How about, the Pursuit of a New Leading Man?

Believe it, Lucas told Fox News, saying that any future installment of the Indy franchise would most likely move forward with Shia LaBeouf's Mutt Williams as the main character, Indy regulated to sidekick status, a la Sean Connery in "Last Crusade."

For his part, LaBeouf -- after a year of couched answers and hiding secrets -- seems positively thrilled at the possibility.

Change that. When MTV News caught up with the precocious young star this morning at the Cannes Film Festival, he seemed downright giddy.

"I don't think a Mutt spinoff would be as big as Indiana Jones," he told MTV. "[But] fingers crossed!"

(Make sure to read about what else LaBeouf said of the prospect, along with Harrison Ford's thoughts here)

But what about us? Obviously so much depends on how LaBeouf fares with critics and fans when "Crystal Skull" opens -- and even if he's a homerun nothing, of course, is a certainty -- but what do you think about an Indiana Jones film without, well, much Indiana Jones? Does LaBeouf have the chops to continue the most iconic franchise of my lifetime? Would you want another group of sequels, or would they diminish the original three (soon four) in your mind?

And while we're at it, how would it work? Sound off on your thoughts, desires, and ideas for where a sequel could go below. The choice is in your hands. Choose...wisely.
