[Update: Producer Frank Marshall labeled this rumor as "completely false"]

Ever since Indiana Jones and The Kingdom of the Crystal Skull banked over $700 million at the worldwide box office there have been rumblings of a fifth Indiana Jones adventure. Harrison Ford, George Lucas and Shia LaBeouf have all mentioned that an idea, if nothing else, is out there - but they failed to elaborate on any details.

Now, we're hearing rumors (take this with a pinch of salt) that Indiana Jones 5 may shoot next year - and that it will see the iconic action hero visit the Bermuda Triangle, with son Mutt tagging along for the ride.Aint It Cool has a posted a scoop from Stuff that seems to purport details about Indiana Jones' next adventure.

The site claims the filmmakers are presumably shooting for a 2012 release, and goes on to state the movie will take the Indy franchise "back to its roots after a badly received fourth installment."

"Indiana Jones 5 will begin shooting next year, and much of the plot line will be centred around the Bermuda Triangle, an area over the North Atlantic Ocean where a number of aircraft are said to have disappeared."

Stuff goes on to report that a "source" said:

"George (Lucas) and Steven (Spielberg) have been working on a script and it's almost there. Harrison is on stand-by for filming next year. This looks like being an emotional and exciting conclusion to the franchise, with Indy facing his biggest challenge yet."

Shia LaBeouf Indiana Jones 5

In regards to Mutt's return:

"Shia LaBeouf has a central role again as Indy's son but this will be a blockbuster made in the old fashioned way rather than the CGI efforts of the last movie."

So, is there any truth to this?

God only knows. If I were a betting man (and I'm not) I'd say it's unlikely - because Lucas and Spielberg like to play these things close to their chests and I doubt there'd be any leaks at this early stage (unless they made one heck of a slip up).

There's a chance that this story could have been an early idea for the fourth film - or another rejected plot. It took almost 20 years for the last Indiana Jones film to make it to the big screen and it would be pretty amazing if they had this in front of cameras by next year.

Having said that, Harrison Ford isn't getting any younger, so another 20 year delay for Indy 5 isn't an option.

So, what do you guys think - Indy in Bermuda shorts?
