Indiana Jones 4, tentatively titled Indiana Jones and the City of the Gods is underway. Earlier this week there was a cattle call for extras in New Haven, Connecticut, and it appears production is underway at the Universal Studios backlot as well.

Filmpub claims to have photos of the construction of a set for Indiana Jones 4, perhaps even a look at the entrance of the City of the Gods. Or, maybe the Czech site just has pictures of a stone wall… or a set from another movie altogether. Who knows.

Not to sound too cynical, but Indy is going to be big news for the next year, which means everyone is going to try and cash in on its popularity. Be wary of everything you see that isn’t officially released by the studio. Of course, it’s always great to find out pictures and information are authentic, but typically that’s only confirmed by the cease and desist letters.

Take a look at Indiana Jones and the Stone Wall and decide for yourself whether they are legitimate.

UPDATE: The new scuttlebut making its way around the web is that these are images from Nic Cage's National Treasure 2, not Indy 4. As I said, take everything with a grain of skeptecism.
