Why does Emmerich think that the British Royal Family is the highest priority?
He had the helicopters freezing up and coming down over Scotland in the extreme cold, and in 2012 he had the Queen with a couple of Corgis boarding the ark.
Seriously, if such disasters were to occur, we would not be saving the Royal Family AT ALL, as they're only there as figureheads to represent our culture and have no real power. And what would be the point? Elizabeth II is too old, and as for the Duke of Edinburgh, he's a definite liability with his reckless driving at his extreme age.
So why would we be saving such old fogies? The Royal Family has not had much influence at all in the last few decades, and it has nearly fractured so many times. In a new world, we should let them die out.
