There is no mistaking it. You need only here a few cords of John Williams score to know Indiana Jones is BACK!! And this time he is chasing after a 61 year old New Mexico legend: The Roswell Incident
...or at least that is the impression in the new preview for INDIANA JONES AND THE KINGDOM OF THE CRYSTAL SKULL:
Granted, the 'crystal skull' is from Aztec times in Old Mexico...I'm guessing the Roswell part of the film is the beginning sequence None the less, I'm pretty psyched about it.
