CHUD has come upon some very interesting details regarding the upcoming fourth installment in the Indiana Jones franchise (which according to them is unofficially titled Indiana Jones and the City of the Gods).
The site reports through their source that the opening action scene will have Dr. Jones coming up against Russian agents in Area 51, a plot element which the site notes is similar to the Frank Darabont draft.
Additionally, the site reports that the basic storyline involves “crystal skulls and takes its cues from Chariots of the Gods.”
