Indy IV and Transformers star Shia LaBeouf has spilled the news that The Beard has "cracked" a plotline for the next Indy movie.
There's still a long time to go until shooting might start, though.
So, before George Lucas gets his clammy hands on the treatment, we not-so-humbly present our own thoughts on what Dr Jones & Son might do next...
1. Indiana Jones And The Tediously Topical Financial Riff
The plot: A prequel, set in 1920s Depression-era America.
Behind the local job centre, a mysterious hooded figure spins out-of-work Indy a curious tale about there having been THREE stone tablets handed to Moses on Mount Sinai, rather than two.
The missing third slab allegedly contains a formula for predicting financial trends eons into the future.
Indy must venture into the network of sub-Sinai caves to retrieve it before the relatively new-fangled Nazis, also on to the rumour, get there first.
The twist: The hooded figure shows up midway through Indy’s mission, and reveals himself to be a senior Vatican official who also seeks the formula for the exclusive benefit of the Roman Catholic church.
The climax: It all goes tits up and Indy is forced to sacrifice the tablet in an erupting volcano - along with the evil Vatican stooge and a busload of mini-Hitlers - in order to escape.
In a 1937 epilogue, a second wave of recession hits America hard. (At which point, cinema-going students of economic history around the world go “Ooh, clever!”)
