With regards to excluding the supernatural, I'd like to see an Indy film where everyone THINKS the Macguffin is of a supernatural nature, only to have it turn out to be nothing of the sort! It'd never happen, but a guy can dream!
Kind of reminds me of Uncharted 3 a bit with the Macguffin hinted at being supernatural but not really after all.
