I've got in my imagination this movie. A mash-up of the Sergio Leone Clint Eastwood spaghetti westerns, and Atlas Shrugged. Some random minor character in a dusty saloon asks "?quien es John Galt?". Cue the good the bad the ugly theme, and in walks the stranger, a gunslinger, oddly familiar, with "a face without pain or fear or guilt." Noone dies, mostly, but people disappear into the desert.
