It's an often lampooned scene towards the end of Superman, when the titular Superman discovers Lois has died, he flies around the world very fast in the opposite direction to its spin.
This apparently causes the Earth to slow down and spin backwards which seems to have the effect of "turning the clock back" and time begins to run in reverse. We've all laughed at the notion that spinning the Earth in the opposite direction could somehow cause time to run backwards.
However, it occurred to me that what might actually be happening is that Superman himself is flying backwards through time. We are simply seeing the world from Superman's point of view (or at least it's the movie's way of telling us "We're going back in time"), and of course if Superman is travelling back in time the world would appear to spin in reverse.
Is this what we're supposed to take from this scene? Has it been discussed by the creators of the movie? And if not, is it a commonly held fan theory?
