The first trailer gave us “Roswell, New Mexico, 1947”. The second trailer gave us a glimpse of the crystal skull, which doesn’t exactly look all that humanoid. And now, the third trailer gives us this aerial shot, which seems to depict the Nazca Lines in Peru. These images are believed to have been created between 200 BC and AD 700, and are said to be visible only from the sky — which has led Chariots of the Gods author Erich von Däniken, among others, to speculate that these images may be evidence of early contact between humans and aliens. And sure enough, there have been rumours for quite some time now that Indiana Jones and the Kingdom of the Crystal Skull may be taking its cues from Chariots of the Gods. Hmmm. We’ll see when the film comes out May 22.
