Script: SUPER-CHRIS flies off into SPACE and, as much as it's still impossible to believe that this was a thing that actually happened in an actual major motion picture, he FLIES AROUND THE EARTH so fast that THE EARTH STARTS SPINNING BACKWARDS, which somehow, SOMEHOW, causes TIME TO REVERSE ITSELF.
SUPER-CHRIS: No, no, that's not what happens! That's how it looks, sure, but in actuality I just fly so fast that I travel back in time, and the Earth APPEARS to spin the other way because that's what it would like from the perspective of somebody traveling backwards through time. It's still scientifically impossible, but not completely droolingly, moronically so!
Script: Uh huh. Then what about the bit at the end, where you clearly stop, and then start flying just as fast in the opposite direction to start the planet spinning correctly again?
SUPER-CHRIS: Oh. That. Well, uh... I guess... damnit. I felt so clever when I came up with that slightly more plausible explanation.
