Well, your explanation (I'll have to listen to the commentary again as I don't remember the filmmakers exact words) would be the equivalent of being able to travel back in time simply by putting your car in reverse and driving backwards. Of course, that is just stupid. I simply cannot believe...
Thank you. Geez, I didn't know this was such a disputed point. It's like the old argument whether or not Palpatine was Sidious. Duh.
Of course the filmmakers can use verbal shorthand and say "Superman spun the Earth backwards". That doesn't necessarily translate to "Superman physically grabbed...
I dunno. I thought it was pretty obvious Superman was flying so fast he travelled back in time. The earth turning backwards was because of time reversing, not the other way around.
Maybe Mank did not explain it well enough in the interview, but I thought it was pretty clear onscreen.
Yes, simply rotating the earth in the opposite direction will not turn back time. But that is not what Superman does. Superman flies faster than the speed of light in order to travel back in time. Kind of the opposite of Einstein's Theory of Relativity.
