Well, this is an interesting find, Dr. Jones. Apparently, a PDF document claiming to be Indiana Jones and the City of the Gods, as written by Frank Darabont, has found its way online. There's no word yet on whether it's the real deal, and I haven't had the time to read through the whole thing, but it might be worth a look. To recap: Frank Darabont (The Shawshank Redemption) wrote an early draft of Indiana Jones and the Kingdom of the Crystal Skull. Legend has it Steven Spielberg really liked his draft, but George Lucas did not. Thus, Darabont eventually left the project -- one he'd worked on tirelessly -- time went by, and David Koepp finally wound up with it.
But what happened to Darabont's unused script -- the one Spielberg apparently loved? Who knows. Some people say aliens took it one night when Darabont wasn't paying attention, while others believe it was buried with one of them rare crystal skulls in the mountains of Peru. Regardless, folks are saying it's now online and you can read it right here. I'd do it fast, though, because someday a crazy wild-eyed scientist or a kid (or an angry studio) might show up lookin' for that there script (which includes both Papa Jones and Marion, by the way).
Again, it could be an elaborate fake. Nevertheless, I suppose you now have something to read while on the shi .... ahem.
