"The Secret Life of Walter Mitty" tells the story of the aging Walter Mitty on a trip into town with his overbearing wife, Mrs. Mitty. Walter is an ineffectual person who spends more time in heroic daydreams than paying attention to the real world, or more seriously, one who intentionally attempts to mislead or convince others that he is something that he is not.
Sound familiar?
There's an old Mormon prophecy—of questionable origin and not accepted as official doctrine by the church—that in the latter days, when the US Constitution is hanging "like a thread," a Mormon will gallop in on a white horse to save the day, and Mormons will take the reins of the US government.
Death rode on a pale horse too.
