The always incomparable California Jack was kind enough to send along the official high-res title design released by Lucasfilm. CLICK IT for a gargantuanly huge version. PREVIOUS REPORTS BELOW!!!

Hey, everyone. "Moriarty" here. Sure enough, the official INDIANA JONES site has confirmed that INDIANA JONES AND THE KINGDOM OF THE CRYSTAL SKULL will be the title of the fourth film when it is released next summer. What's fascinating about all of this is how everything I've heard about this film... EVERYTHING... makes it sound like they're basically just using the Frank Darabont script that Lucas made so many comments about a few years ago. For a script that was so far from ready, it sure seems like Lucas was happy to cannibalize it for the final version. I'm sure we'll have more details for you in the months ahead, as this thing's basically wrapped up and ready to head into post now. Here's the original report Merrick ran earlier:

So, my son comes running into the room while I'm eating dinner and tells me that Shia LaBeouf was just on the VMAs (Video Music Awards) on MTV. While presenting an award, Shia indicated he'd been sworn to secrecy by Lucas and Spielberg regarding details of the next INDIANA JONES movie...then went on to note he was in Vegas...and he is now 21...so... Shia said... ...the film... ...is called...

INDIANA JONES AND THE KINGDOM OF THE CRYSTAL SKULL

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! So, that's what Shia called it...for whatever it's worth. I'm going back to my dinner now. Who says MTV is good for nothing these days?
